Atlantic Tropical Weather Outlook

2021-05-22 07:33:06| National Hurricane Center (Atlantic)

000 ABNT20 KNHC 220532 TWOAT 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: 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. 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 Forecast Office. * Formation chance through 48 hours...low...30 percent. * Formation chance through 5 days...low...30 percent. && High Seas Forecasts issued by the National Weather Service can be found under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php $$ Forecaster Cangialosi

Atlantic Tropical Weather Outlook

2021-05-22 01:20:03| National Hurricane Center (Atlantic)

000 ABNT20 KNHC 212319 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 PM EDT Fri May 21 2021 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Recent satellite images indicate that the area of low pressure located about 250 miles northeast of Bermuda is well-defined and is gradually acquiring subtropical characteristics. In addition, earlier satellite-derived wind data revealed that the system is producing gale-force winds. The associated shower and thunderstorm activity has increased slightly over the past several hours. If that trend continues, it would result in advisories being initiated on the system later tonight or Saturday morning while it moves slowly westward to west-southwestward to the northeast of Bermuda. The low is forecast to move northeastward into a more hostile environment by Saturday night or Sunday and the systems development chances diminish after that time. 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...90 percent. * Formation chance through 5 days...high...90 percent. A well-defined low pressure area is located over the western Gulf of Mexico about 150 miles east-southeast of Corpus Christi, Texas. Earlier satellite wind data and buoy observations indicated that the system is producing winds of 30-35 mph near and to the east of its center but recent satellite and radar imagery shows that shower and thunderstorm activity remains limited. Although environmental conditions are not particularly favorable for significant development, only a slight increase in thunderstorm activity could result in the formation of a tropical depression or storm before the system moves inland along the Texas coast overnight. Regardless of development, the system could produce heavy rainfall over portions of southeastern Texas and southwestern Louisiana through Saturday. 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 Forecast Office. * Formation chance through 48 hours...medium...50 percent. * Formation chance through 5 days...medium...50 percent. && High Seas Forecasts issued by the National Weather Service can be found under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php $$ Forecaster Latto/Brown

Atlantic Tropical Weather Outlook

2021-05-21 22:08:22| National Hurricane Center (Atlantic)

000 ABNT20 KNHC 211750 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 PM EDT Fri May 21 2021 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Showers and thunderstorms associated with a non-tropical low pressure area centered about 300 miles northeast of Bermuda have diminished somewhat over the past several hours, and the system has not yet acquired subtropical storm characteristics. However, any increase in organization would result in advisories being initiated on the system later today or tonight as it moves westward to west-southwestward to the northeast of Bermuda. Subsequently, the low is forecast to move northeastward into a more hostile environment by Saturday night or 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...90 percent. * Formation chance through 5 days...high...90 percent. Surface observations and recent satellite wind data indicate that a well-defined low pressure system over the western Gulf of Mexico has winds of 30-35 mph near and east of the center. The associated shower and thunderstorm activity remains limited, but any increase in this activity may result in the formation of a short-lived tropical depression or storm before the system moves inland over the northwestern Gulf coast tonight, and potential tropical cyclone advisories may be needed as early as this afternoon. Regardless of development, the system could produce heavy rainfall over portions of southeastern Texas and southwestern Louisiana through Saturday. 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 Forecast Office. * Formation chance through 48 hours...medium...60 percent. * Formation chance through 5 days...medium...60 percent. && High Seas Forecasts issued by the National Weather Service can be found under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php $$ Forecaster Beven/Papin
