000 ABNT20 KNHC 271136 TWOAT TROPICAL WEATHER OUTLOOK NWS NATIONAL HURRICANE CENTER MIAMI FL 800 AM EDT SUN SEP 27 2015 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Tropical Depression Ida, located a little more than 1000 miles east-northeast of the northern Leeward Islands. An area of low pressure over the northeastern Yucatan Peninsula and an upper-level low pressure system over the western Gulf of Mexico are producing a large area of disorganized cloudiness and showers extending from the northwestern Caribbean Sea northward over the eastern Gulf of Mexico. Upper-level winds are expected to be only marginally conducive for development while this system moves northward toward the northern Gulf Coast during the next couple of days. Regardless of tropical cyclone formation, this disturbance is likely to produce locally heavy rainfall over portions of the northern Gulf Coast and southeastern United States during the next several days. An Air Force Reserve reconnaissance aircraft is scheduled to investigate this system later today, if necessary. For additional information on this system, see High Seas Forecasts issued by the National Weather Service and products from your local National Weather Service office. * Formation chance through 48 hours...low...30 percent * Formation chance through 5 days...low...30 percent Showers and thunderstorms are showing signs of organization in association with an area of low pressure located about 425 miles south-southwest of Bermuda. Some additional development of this system is possible and this system could become a tropical depression during the next day or so while it moves toward the northwest at 5 to 10 mph. After that time, development is not expected due to unfavorable upper-level winds. For additional information on this system, see High Seas Forecasts issued by the National Weather Service. * 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 on the Web at http://www.opc.ncep.noaa.gov/shtml/NFDHSFAT1.shtml. $$ Forecaster Cangialosi

000 ABNT20 KNHC 262331 TWOAT TROPICAL WEATHER OUTLOOK NWS NATIONAL HURRICANE CENTER MIAMI FL 800 PM EDT SAT SEP 26 2015 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Tropical Depression Ida, located a little more than 1000 miles east-northeast of the northern Leeward Islands. An area of low pressure located over the eastern Yucatan Peninsula is producing disorganized showers and thunderstorms and gusty winds over portions of the northwestern Caribbean Sea, the southeastern Gulf of Mexico, and the Yucatan Peninsula. This system is expected to move northward at about 10 mph into the southern Gulf of Mexico on Sunday and should then move more quickly northward or northeastward as it interacts with an upper-level low near the Texas coast. While upper-level winds are only expected to be marginally conducive, there is some potential for this system to become a tropical cyclone during the next couple of days before it reaches the northern Gulf Coast. Regardless of tropical cyclone formation, this disturbance is likely to produce locally heavy rainfall over portions of the northern Gulf Coast and southeastern United States early next week. An Air Force Reserve reconnaissance aircraft is scheduled to investigate this system tomorrow, if necessary. For additional information on this system, see High Seas Forecasts issued by the National Weather Service and products from your local National Weather Service office. * Formation chance through 48 hours...medium...40 percent * Formation chance through 5 days...medium...40 percent Satellite imagery indicates that a weak area of surface low pressure has formed about 450 miles south-southwest of Bermuda, and the associated shower and thunderstorm activity has increased since yesterday. Some additional gradual development of this system is possible during the next couple of days while it moves toward the north-northwest or northwest at 5 to 10 mph. After that time, development is not expected due to unfavorable upper-level winds. * Formation chance through 48 hours...medium...40 percent * Formation chance through 5 days...medium...40 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 Brennan

000 ABNT20 KNHC 261734 TWOAT TROPICAL WEATHER OUTLOOK NWS NATIONAL HURRICANE CENTER MIAMI FL 200 PM EDT SAT SEP 26 2015 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Tropical Depression Ida, located a little more than 1000 miles east-northeast of the northern Leeward Islands. Visible satellite images and surface observations indicate that a low pressure area has formed over the southeastern portion of the Yucatan Peninsula. This low is producing disorganized showers and thunderstorms and gusty winds over portions of the northwestern Caribbean Sea and the Yucatan Peninsula. This system is expected to reach the southern Gulf of Mexico on Sunday and should continue to move northward thereafter while it interacts with an upper-level low near the Texas coast. During this interaction, there is some potential for the system to become a tropical cyclone. Regardless of tropical cyclone formation, this disturbance is likely to produce locally heavy rainfall over portions of the northern Gulf coast and southeastern United States early next week. An Air Force Reserve reconnaissance aircraft is scheduled to investigate this system on Sunday, if necessary. * Formation chance through 48 hours...low...30 percent * Formation chance through 5 days...medium...40 percent Disorganized showers and thunderstorms over the western Atlantic Ocean several hundred miles south-southwest of Bermuda are associated with an upper-level low and a surface trough. Some slow development of this system is possible during the next day or two while it moves toward the north or north-northwest. After that time, development is not expected due to unfavorable upper-level winds. * Formation chance through 48 hours...low...20 percent * Formation chance through 5 days...low...20 percent $$ Forecaster Cangialosi/Beven

000 ABNT20 KNHC 261131 TWOAT TROPICAL WEATHER OUTLOOK NWS NATIONAL HURRICANE CENTER MIAMI FL 800 AM EDT SAT SEP 26 2015 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Tropical Depression Ida, located a little more than 1000 miles east-northeast of the northern Leeward Islands. A trough of low pressure is producing a large area of disorganized cloudiness and thunderstorms over the northwestern Caribbean Sea, the Yucatan Peninsula, and northern portions of Central America. This system is expected to reach the southern Gulf of Mexico later this weekend, and will begin to interact with an upper-level low located near the Texas coast. This interaction should result in the development of a broad and complex area of low pressure that moves northward over the Gulf of Mexico early next week. Although environmental conditions are not expected to be conducive for tropical cyclone formation, this disturbance is likely to produce locally heavy rainfall over portions of the northern Gulf coast and southeastern United States early next week. * Formation chance through 48 hours...low...10 percent * Formation chance through 5 days...low...20 percent Disorganized showers and thunderstorms over the western Atlantic Ocean several hundred miles south-southwest of Bermuda are associated with an upper-level low and a surface trough. Development, if any, of this system is expected to be slow to occur while it moves toward the north or north-northwest. Upper-level winds are forecast to become unfavorable for development after the weekend. * Formation chance through 48 hours...low...10 percent * Formation chance through 5 days...low...10 percent $$ Forecaster Cangialosi/Kimberlain
