000 ABNT20 KNHC 242332 TWOAT TROPICAL WEATHER OUTLOOK NWS NATIONAL HURRICANE CENTER MIAMI FL 800 PM EDT WED AUG 24 2016 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Tropical Storm Gaston, located about 1100 miles west of the Cabo Verde Islands. A broad area of low pressure centered about 100 miles north of Puerto Rico is producing gale-force winds over water to the north of the Lesser Antilles. However, satellite images indicate that shower activity has become less organized than earlier today, and the low continues to lack a well-defined center. Although upper- level winds are only marginally conducive for development, this system could still become a tropical cyclone during the next couple of days. Environmental conditions have the potential to become more conducive for development over the weekend when the system is near the central or northwestern Bahamas. Regardless of development, gusty winds, heavy rains, and possible flash floods and mudslides are likely to occur over portions of the Leeward Islands, Puerto Rico, Hispaniola, and the southeastern and central Bahamas during the next couple of days. Please consult products issued by your local meteorological offices and High Seas Forecasts from the National Weather Service for further details. Interests in the northwestern Bahamas and Florida should monitor the progress of this disturbance. Because of the large uncertainties regarding this system's development and future track, it is too early to speculate on what specific impacts might occur in the northwestern Bahamas, Florida or beyond. * Formation chance through 48 hours...medium...50 percent * Formation chance through 5 days...high...80 percent && High Seas Forecasts issued by the National Weather Service can be found under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and on the Web at http://www.opc.ncep.noaa.gov/shtml/NFDHSFAT1.shtml. $$ Forecaster Blake

000 ABNT20 KNHC 241750 TWOAT TROPICAL WEATHER OUTLOOK NWS NATIONAL HURRICANE CENTER MIAMI FL 200 PM EDT WED AUG 24 2016 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Tropical Storm Gaston, located about 1000 miles west of the Cabo Verde Islands. A strong tropical wave and associated broad area of low pressure is moving westward across the northern Leeward Islands and Puerto Rico. Reports from an Air Force Reconnaissance aircraft and surface observations indicate that the system still lacks a well-defined circulation, but it nevertheless is producing tropical-storm-force winds in squalls over the northernmost Leeward Islands and adjacent waters. Although upper-level winds are expected to be only marginally conducive for additional development, this system could become a tropical storm or tropical depression at any time during the next couple of days. Environmental conditions could become more conducive for development by the weekend when the system is near the central or northwestern Bahamas. Regardless of development, squalls to tropical storm force can be expected over portions of the northern Leeward Islands and the northern U.S. and British Virgin Islands this afternoon. Strong winds, heavy rains, and possible flash floods and mudslides are expected to occur over portions of the Leeward Islands, Puerto Rico, Hispaniola, and the southeastern and central Bahamas during the next couple of days. Please consult products issued by your local meteorological offices and High Seas Forecasts from the National Weather Service for further details. Interests in the northwestern Bahamas and Florida should monitor the progress of this disturbance. Because of the large uncertainties regarding this system's development and future track, it is too early to speculate on what specific impacts might occur in the northwestern Bahamas, Florida or beyond. * Formation chance through 48 hours...medium...60 percent * Formation chance through 5 days...high...80 percent && High Seas Forecasts issued by the National Weather Service can be found under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and on the Web at http://www.opc.ncep.noaa.gov/shtml/NFDHSFAT1.shtml. $$ Forecaster Brown

The National Hurricane Center is issuing advisories on Tropical Storm Gaston, located about 1000 miles west of the Cabo Verde Islands. Updated: An Air Force Reconnaissance aircraft currently investigating the broad low pressure area and tropical wave near the northern Leeward Islands has found winds to tropical storm force in a few squalls near the northernmost Leeward Islands. Squalls to tropical storm force can be expected over the extreme northern Leeward Islands and portions of the northern U.S. and British Virgin Islands this afternoon. The reconnaissance aircraft mission is ongoing to determine whether or not a tropical cyclone has formed. Although environmental conditions are currently only marginally conducive for additional development, this system could become a tropical depression or tropical storm at any time during the next few days while it moves west-northwestward at about 15 mph across the northern Leeward Islands, near or over Puerto Rico, Hispaniola, and the Bahamas. Strong winds, heavy rains, and possible flash floods and mudslides are expected to occur over portions of the Leeward Islands, Puerto Rico, Hispaniola, and the southeastern and central Bahamas. Please consult products issued by your local meteorological offices for further details. Interests in the northwestern Bahamas and Florida should also monitor the progress of this system. * Formation chance through 48 hours...medium...60 percent * Formation chance through 5 days...high...80 percent $$ Forecaster Brown

Satellite images, surface observations, and radar data indicate that a broad area of low pressure associated with a tropical wave is located over the northern Leeward Islands. Showers and thunderstorms have become more concentrated overnight and are showing signs of organization, but the system still appears to lack a well-defined circulation. Although environmental conditions are currently only marginally conducive for additional development, this system could become a tropical depression at any time during the next few days while it moves west-northwestward at about 15 mph across the northern Leeward Islands, near or over Puerto Rico, Hispaniola, and the Bahamas. An Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate the disturbance late this morning. Gusty winds, heavy rains, and possible flash floods and mudslides are expected to occur over portions of the Leeward Islands, Puerto Rico, Hispaniola, and the southeastern and central Bahamas. Please consult products issued by your local meteorological offices for further details.

000 ABNT20 KNHC 240506 TWOAT TROPICAL WEATHER OUTLOOK NWS NATIONAL HURRICANE CENTER MIAMI FL 200 AM EDT WED AUG 24 2016 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Tropical Storm Gaston, located several hundred miles west of the Cabo Verde Islands. Satellite images, surface observations, and radar data from the Lesser Antilles indicate that a broad area of low pressure associated with a tropical wave is located near Guadeloupe. Although environmental conditions are only marginally conducive for development, this system could become a tropical depression during the next day or two while it moves west-northwest at 15 to 20 mph across the Leeward Islands and the Greater Antilles. Conditions could become more conducive later this week while the system moves near the southeastern and central Bahamas. An Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate this disturbance later today, if necessary. Interests from the islands of the northeastern Caribbean Sea to the Bahamas should continue to monitor the progress of this system. Gusty winds, heavy rains, and possible flash floods and mudslides could occur over portions of these areas regardless of tropical cyclone formation. Please consult products issued by your local meteorological offices for further details. * Formation chance through 48 hours...medium...50 percent * Formation chance through 5 days...high...70 percent $$ Forecaster Stewart
