Tropical Depression Nineteen Forecast Discussion Number 3

Tropical Depression Nineteen Discussion Number   3
NWS National Hurricane Center Miami FL       AL192024
400 AM EST Thu Nov 14 2024
 
The satellite presentation of the system has gradually been 
improving.  The latest subjective intensity estimates from TAFB and 
SAB are both T-2.0/30 kt.  Based on the subjective Dvorak estimates 
and the improvement in the convective structure noted on satellite 
imagery, the system is upgraded to a tropical depression.  This is 
supported by data from the Indian Oceansat scatterometer, which 
shows a well-defined circulation.  The intensity is set to 30 kt 
based on the Dvorak estimates.
 
Tropical Depression Nineteen has been moving faster, just south of 
due west, or 265/14 kt, although it should begin slowing down later 
today.  A mid-level ridge centered to the north of the depression 
over the Straits of Florida should keep it on a westward track until 
Friday, taking the system near the north coast of eastern Honduras, 
and possibly inland.  After that, the ridge is expected to break 
down, and the models agree that the cyclone will meander in weak 
steering currents late Friday through the weekend.  This expected 
slow motion will cause the system to produce heavy rains over the 
same region, likely causing life-threatening flooding over portions 
of Central America.  By early next week, ridging should become 
re-established over Florida and the eastern Gulf of Mexico, which 
should cause the system to move northwestward across Belize and the 
Yucatan Peninsula.  Very little change was made to the first 3 days 
of the track forecast.  Beyond day 3, there has been a notable 
westward shift in the track guidance.  The NHC forecast is a bit 
west of the previous forecast beyond day 3, but not as far west as 
the bulk of the latest model guidance.
 
Environmental conditions are conducive for intensification during 
the next day or two while the system remains over water, with low 
vertical wind shear and relatively high mid-level humidities. 
However, there is a significant amount of uncertainty in how much 
land interaction with Honduras occurs.  The majority of the models 
are showing the center move just barely inland over Honduras, or 
parking it right on the coastline, between hour 48 and 72. However, 
if the system stays offshore, as shown by the latest HWRF model 
solution, it could take advantage of the conducive atmospheric and 
oceanic conditions and continue to strengthen.  The latest NHC 
intensity forecast is similar to the previous one through 36 h, but 
then is about 5 kt lower than the previous forecast since this 
forecast shows a bit more land interaction beyond 36 h.  The latest 
NHC intensity forecast is above the high end of the guidance 
envelope beyond 36 h.
 
KEY MESSAGES:
 
1. Through early next week, heavy rainfall will cause significant,
life-threatening flash flooding and mudslides across portions of
Central America, particularly Honduras, Belize, El Salvador, eastern
Guatemala, and western Nicaragua.
 
2. The disturbance is forecast to be near hurricane strength when
it moves near the eastern coast of Honduras on Friday and Saturday.
Hurricane watches and tropical storm warnings are in effect for
portions of that area.
 
3. The system is forecast to approach Belize and the Yucatan
Peninsula of Mexico at or near hurricane strength by early next week
where there is a risk of dangerous storm surge and damaging winds.
Residents in these areas should monitor the latest forecast updates
and ensure that they have their hurricane plan in place.
 
4. It is too soon to determine what impacts the system could bring
to portions of the eastern Gulf of Mexico, including Florida, the
Florida Keys, and Cuba during the middle portion of next week.
Residents in these areas should regularly monitor updates to the
forecast.

Article Alert: Indirect interactions among tropical tree species through shared rodent seed predators: a novel mechanism of tree species coexistence

A new aticle published in Ecology Letters  looks into the indirect interactions among tropical tree species through shared rodent seed predators. The reasearch is part of the work of EU BON postdoc Carol X. Garzon-Lopez.

Abstract: The coexistence of numerous tree species in tropical forests is commonly explained by negative dependence of recruitment on the conspecific seed and tree density due to specialist natural enemies that attack seeds and seedlings (‘Janzen–Connell’ effects). Less known is whether guilds of shared seed predators can induce a negative dependence of recruitment on the density of different species of the same plant functional group. We studied 54 plots in tropical forest on Barro Colorado Island, Panama, with contrasting mature tree densities of three coexisting large seeded tree species with shared seed predators. Levels of seed predation were far better explained by incorporating seed densities of all three focal species than by conspecific seed density alone. Both positive and negative density dependencies were observed for different species combinations. Thus, indirect interactions via shared seed predators can either promote or reduce the coexistence of different plant functional groups in tropical forest.

Article Alert: New TEAM network paper looks at standardized assessment of biodiversity trends in tropical forest protected areas

The Tropical Ecology Assessment and Monitoring (TEAM) network has the aim to measure and compare plants, terrestrial mammals, ground-dwelling birds and climate using a standard methodology in a range of tropical forests, from relatively pristine places to those most affected by people. TEAM currently operates in sixteen tropical forest sites across Africa, Asia and Latin America supporting a network of scientists committed to standardized methods of data collection to quantify how plants and animals respond to pressures such as climate change and human encroachment.

A recent TEAM network paper published in PLOS Biology deals with the standartization of methods in assessing biodiversity trends in tropical forest protected areas.

Abstract: 

Extinction rates in the Anthropocene are three orders of magnitude higher than background and disproportionately occur in the tropics, home of half the world’s species. Despite global efforts to combat tropical species extinctions, lack of high-quality, objective information on tropical biodiversity has hampered quantitative evaluation of conservation strategies. In particular, the scarcity of population-level monitoring in tropical forests has stymied assessment of biodiversity outcomes, such as the status and trends of animal populations in protected areas. Here, we evaluate occupancy trends for 511 populations of terrestrial mammals and birds, representing 244 species from 15 tropical forest protected areas on three continents. For the first time to our knowledge, we use annual surveys from tropicalforests worldwide that employ a standardized camera trapping protocol, and we compute data analytics that correct for imperfect detection. We found that occupancy declined in 22%, increased in 17%, and exhibited no change in 22% of populations during the last 3–8 years, while 39% of populations were detected too infrequently to assess occupancy changes. Despite extensive variability in occupancy trends, these 15 tropical protected areas have not exhibited systematic declines in biodiversity (i.e., occupancy, richness, or evenness) at the community level. Our results differ from reports of widespread biodiversity declines based on aggregated secondary data and expert opinion and suggest less extreme deterioration in tropical forest protected areas. We simultaneously fill an important conservation data gap and demonstrate the value of large-scale monitoring infrastructure and powerful analytics, which can be scaled to incorporate additional sites, ecosystems, and monitoring methods. In an era of catastrophic biodiversity loss, robust indicators produced from standardized monitoring infrastructure are critical to accurately assess population outcomes and identify conservation strategies that can avert biodiversity collapse.

The conference will run from April 02 to 05, 2013 in Vienna, Austria. The conference aims at maximizing interactions among scientists of all disciplines and backgrounds who are interested in tropical ecology and biodiversity.
Ongoing global change processes along the inter-twined dimensions of climate and land-use pose tremendous challenges for maintaining ecosystem functions. Traditionally, ecological research on climate change had its focus on high altitude and latitude biomes that severely and rapidly suffer from warming. Yet, effects of climate change on tropical ecosystems and organisms can be equally strong. In addition, changes in land-use exert ever increasing pressures especially on tropical biota. Understanding these processes is crucial to allow for predicting and mitigating adverse effects of forthcoming changes on tropical biodiversity and its role in ecosystem functioning. The annual conference of the Society for Tropical Ecology (gtö) will provide an interdisciplinary platform for discussion, particularly on the following topics:
- Climate change effects on tropical biota
- Influence of land-use changes on tropical biota
- Tropical biodiversity and ecosystem functioning under Global Change

European Conference of Tropical Ecology

The "European Conference of Tropical Ecology" - the annual scientific meeting of the Society for Tropical Ecology (Gesellschaft für Tropenökologie, gtö) - will be organized in 2017 in Brussels, Belgium, by three Universities and three research-museum institutions. It will take place from Monday 6 to Friday 10 February 2017, on the campus "Etterbeek" from the Vrije Universiteit Brussel, a location easily reached from the city centre by public transport. 

The overarching topic will be "(re)connecting tropical biodiversity in space and time". It highlights both the importance of integrating fundamental sciences inferring past processes (e.g. paleoecology, evolution, social history…) to understand current patterns of biodiversity, and the urgent need to reconnect patches of fragmented landscapes if we wish to conserve tropical biodiversity and ecological services of tropical ecosystems for future generations.

Improving the reliability of small- and wide-angle X-ray scattering measurements of anisotropic precipitates in metallic alloys using sample rotation

Rotations of small- and wide-angle X-ray scattering samples during acquisition are shown to give a drastic improvement in the reliability of the characterization of anisotropic precipitates in metallic alloys.

Improving the reliability of small- and wide-angle X-ray scattering measurements of anisotropic precipitates in metallic alloys using sample rotation

Nanometric precipitates in metallic alloys often have highly anisotropic shapes. Given the large grain size and non-random texture typical of these alloys, performing small- and wide-angle X-ray scattering (SAXS/WAXS) measurements on such samples for determining their characteristics (typically size and volume fraction) results in highly anisotropic and irreproducible data. Rotations of flat samples during SAXS/WAXS acquisitions are presented here as a solution to these anisotropy issues. Two aluminium alloys containing anisotropic precipitates are used as examples to validate the approach with a −45°/45° angular range. Clear improvements can be seen on the SAXS I(q) fitting and the consistency between the different SAXS/WAXS measurements. This methodology results in more reliable measurements of the precipitate's characteristics, and thus allows for time- and space-resolved measurements with higher accuracy.

Lattice symmetry relaxation as a cause for anisotropic line broadening and peak shift in powder diffraction

In powder diffraction, lattice symmetry relaxation causes a peak to split into several components which are not resolved if the degree of desymmetrization is small (pseudosymmetry). Here the equations which rule peak splitting are elaborated for the six minimal symmetry transitions, showing that the resulting split peaks are generally broader and asymmetric, and suffer an hkl-dependent displacement with respect to the high-symmetry parent peak. These results will be of help in Rietveld refinement of pseudosymmetric structures where an exact interpretation of peak deformation is required.

Borotropic shifting of the hydro­tris­[3-(2-furyl)pyrazol-1-yl]borate ligand in high-coordinate lan­tha­nide com­plexes

The coordination of hydro­tris­[3-(2-furyl)pyrazol-1-yl]borate (Tp2-Fu, C21H16BN6O3) to lan­tha­nide(III) ions is achieved for the first time with the com­plex [Ln(Tp2-Fu)2](BPh4)·xCH2Cl2 (1-Ln has Ln = Ce and x = 2; 1-Dy has Ln = Dy and x = 1). This was accom­plished via both hydrous (Ln = Ce) and anhydrous methods (Ln = Dy). When isolating the dysprosium analogue, the filtrate produced a second crop of crystals which were revealed to be the 1,2-borotropic-shifted product [Dy(κ4-Tp2-Fu)(κ5-Tp2-Fu*)](BPh4) (2) {Tp2-Fu* = hydro­bis­[3-(2-furyl)pyrazol-1-yl][5-(2-furyl)pyrazol-1-yl]borate}. We con­clude that the pres­ence of a strong Lewis acid and a sterically crowded coordination environment are contributing factors for the 1,2-borotropic shifting of scorpionate ligands in conjunction with the size of the conical angle with the scorpionate ligand.

Cocrystals of a coumarin derivative: an efficient approach towards anti-leishmanial cocrystals against MIL-resistant Leishmania tropica

Leishmaniasis is a neglected parasitic tropical disease with numerous clinical manifestations. One of the causative agents of cutaneous leishmaniasis (CL) is Leishmania tropica (L. tropica) known for causing ulcerative lesions on the skin. The adverse effects of the recommended available drugs, such as amphotericin B and pentavalent antimonial, and the emergence of drug resistance in parasites, mean the search for new safe and effective anti-leishmanial agents is crucial. Miltefosine (MIL) was the first recommended oral medication, but its use is now limited because of the rapid emergence of resistance. Pharmaceutical cocrystallization is an effective method to improve the physicochemical and biological properties of active pharmaceutical ingredients (APIs). Herein, we describe the cocrystallization of coumarin-3-carb­oxy­lic acid (CU, 1a; 2-oxobenzo­pyrane-3-carb­oxy­lic acid, C10H6O4) with five coformers [2-amino-3-bromo­pyridine (1b), 2-amino-5-(tri­fluoro­methyl)-pyridine (1c), 2-amino-6-methyl­pyridine (1d), p-amino­benzoic acid (1e) and amitrole (1f)] in a 1:1 stoichiometric ratio via the neat grinding method. The cocrystals 2–6 obtained were characterized via single-crystal X-ray diffraction, powder X-ray diffraction, differential scanning calorimetry and thermogravimetric analysis, as well as Fourier transform infrared spectroscopy. Non-covalent interactions, such as van der Waals, hydrogen bonding, C—H⋯π and π⋯π interactions contribute significantly towards the packing of a crystal structure and alter the physicochemical and biological activity of CU. In this research, newly synthesized cocrystals were evaluated for their anti-leishmanial activity against the MIL-resistant L. tropica and cytotoxicity against the 3T3 (normal fibroblast) cell line. Among the non-cytotoxic cocrystals synthesized (2–6), CU:1b (2, IC50 = 61.83 ± 0.59 µM), CU:1c (3, 125.7 ± 1.15 µM) and CU:1d (4, 48.71 ± 0.75 µM) appeared to be potent anti-leishmanial agents and showed several-fold more anti-leishmanial potential than the tested standard drug (MIL, IC50 = 169.55 ± 0.078 µM). The results indicate that cocrystals 2–4 are promising anti-leishmanial agents which require further exploration.

Tropical Storm Elsa Is Lashing Cuba And Has Florida Next In Its Sights

Dan Charles | NPR

Updated July 5, 2021 at 11:33 AM ET

A tropical storm with 65-mile-an-hour winds is drenching Cuba, and is expected to reach Key West and the west coast of Florida within the next 48 hours.

The National Hurricane Center expects Tropical Storm Elsa to drop between 5 and 10 inches of rain on central and western Cuba, leading to significant flooding and mudslides. The storm probably will weaken somewhat as it crosses the island, but could strengthen again as it approaches Florida.

According to the Associated Press, Cuban officials evacuated 180,000 people as a precaution against the possibility of heavy flooding.

Most of those evacuated stayed at relatives' homes, others went to government shelters, and hundreds living in mountainous areas took refuge in caves prepared for emergencies. The storm had killed at least three people on other Caribbean islands before it reached Cuba

The National Weather Service says that the western coast of Florida, including Tampa Bay, can expect a storm surge that would lift water levels between two and four feet. Much of Florida could see heavy rainfall that could reach six inches in some places. The storm will then bring heavy rains to Georgia and the Carolinas later in the week.

Florida officials were worried that the storm could destabilize what was left of the condominium building that partially collapsed over a week ago. In order to avoid an uncontrolled collapse, they approved the demolition of the remaining portion of the building, which took place on Sunday night.

"The hurricane was coming, the potential for that building to fall on the pile with the victims in it was a tragic thought," Surfside Mayor Charles Burkett told NPR on Monday.

It's early in the hurricane season. The National Oceanic and Atmospheric Administration has predicted a busier-than-average Atlantic hurricane season, but it would be hard to top last year's, which set an all-time record with 30 named storms.

Tropical storms are fueled by warm water in the upper layers of the ocean, and ocean temperatures have been rising as heat is trapped by greenhouse gases.
