Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Sat May 22 2021
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
1. Satellite images indicate that the well-defined low pressure area
located about 200 miles northeast of Bermuda continues to produce
gale-force winds and appears to have acquired subtropical
characteristics. In addition, thunderstorm activity has been
gradually increasing near the center, and if that trend continues
advisories will be issued later this morning. The low is expected
to move little today, remaining in the vicinity of Bermuda, but it
is forecast to turn northeastward and move into a more hostile
environment on Sunday. Additional information on this low pressure
area can be found in High Seas forecasts issued by the NOAA Ocean
Prediction Center and forecast products, including a tropical storm
watch, issued by the Bermuda Weather Service.
* Formation chance through 48 hours...high...near 100 percent.
* Formation chance through 5 days...high...near 100 percent.
2. A well-defined low pressure area is approaching the Texas coast and
is now about 50 miles east-southeast of Corpus Christi. Surface
observations and satellite wind data indicate that the system
continues to produce winds of about 35 mph near and to the east of
its center, but the associated shower and thunderstorm activity
remains limited. Since the low is expected to move inland during
the next several hours, the chances of it becoming a tropical
depression or storm are decreasing. Regardless of development,
the system could produce heavy rainfall over portions of
southeastern Texas and southwestern Louisiana today. Given the
complete saturation of soils with ongoing river flooding along the
Texas and Louisiana coastal areas, heavy rain could lead to flash,
urban, and additional riverine flooding across this region.
Additional information on the rainfall and flooding potential can be
found in products issued by your local National Weather Service
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...low...30 percent.
