Tropical Weather Outlook
NWS National Hurricane Center Miami FL
100 PM EST Wed Nov 15 2023
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
1. Southwestern Caribbean Sea:
Disorganized showers and thunderstorms persist in association with a
trough of low pressure located in the southwestern Caribbean Sea.
Environmental conditions appear marginally conducive for development
of this system over the next couple of days, and a tropical
depression could form by this weekend as the system starts moving
northeastward across the western and central part of the Caribbean
Sea. An Air Force Reserve reconnaissance mission is scheduled to
investigate the system tomorrow.
Regardless of development, this system is expected to produce heavy
rains that could result in flash flooding and mudslides over
portions of the Caribbean coast of Central America and the Greater
Antilles through this weekend. Interests in Jamaica, Cuba, Haiti,
the Dominican Republic, the southeastern Bahamas, and the Turks and
Caicos Islands should continue to monitor the progress of this
system.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 7 days...medium...50 percent.
2. Offshore Southeast Coast of United States:
A non-tropical area of low pressure is expected to form near
southern Florida along a frontal boundary by tomorrow. This system
is then forecast to move quickly northeastward across the Bahamas
and offshore of the east coast of the U.S. through the weekend.
Although development into a tropical cyclone appears unlikely, this
system is expected to produce gusty winds and heavy rains across
portions of southern Florida, the Florida Keys, and the Bahamas
during the next couple of days. For more information on this
system, including gale warnings, see High Seas Forecasts issued by
the National Weather Service.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.

Areas affected...portions of the Florida Keys
Concerning...Severe potential...Watch unlikely
Valid 151751Z - 152015Z
Probability of Watch Issuance...5 percent
SUMMARY...A brief tornado/waterspout is possible over the Florida
Keys over the next few hours. A WW issuance is not expected.
DISCUSSION...Thunderstorms have been percolating in intensity over
the past few hours around the FL Keys, some of which have shown
occasional instances of transient low-level rotation. Mid-level
lapse rates remain poor over the region. However, the combination of
surface heating amid mid 70s F surface dewpoints should support
500-1000 J/kg of tall and thin SBCAPE through the afternoon.
Coinciding the buoyancy axis should be increasing 850 mb flow, which
would support modestly curved low-level hodographs. As such, the
stronger, more persistent thunderstorms should continue to exhibit
at least brief periods of low-level rotation and a tornado (or
tornadic waterspout) remains possible around the FL Keys through the
afternoon hours. The tornado threat however is quite sparse, so a
Tornado Watch issuance is not anticipated.
