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.

In an exclusive with ISHN magazine, outgoing ASSE President Rick Pollock explains the profession’s expanding focus on risk and myths about human performance, as well as other issues. “ASSE now has, and will into the future, have a much greater focus on risk. Clearly, any true business leader understands the concept of risk as it applies to investment and decision making. Business is about understanding enterprise risk and how investment is always at risk of loss or under performance."
