GOHSEP Special Weather Report

26 September 2015

As of 2:30 pm


State EOC Activation Level: (CAT) Crisis Action Team


Tropical Weather Outlook: The National Hurricane Center is currently monitoring Tropical Depression Ida and two (2) additional disturbances in the Atlantic, Caribbean and the Gulf of Mexico Region.


Disturbance 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 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 southern United States early next week. An Air Force Reserve reconnaissance aircraft is scheduled to investigate this system on Sunday, if necessary. There is a low (30%) chance of formation over the next 48 hours and a medium (40%) chance of development through the next five days.


Disturbance 2 – Disorganized showers and thunderstorms over the western Atlantic Ocean several hundred miles south-southwest of Bermuda are associated with 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 northwest. After that time, development is not expected due to unfavorable upper-level winds. There is a low (20%) chance of formation through the next five days.
