ZCZC MIATWOAT ALL TTAA00 KNHC DDHHMM 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. 1. 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 2. 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
