Tropical Weather Outlook

NWS National Hurricane Center - Miami, Florida
8:00 AM EDT Thursday September 1, 2011

For the north Atlantic Caribbean Sea and the Gulf of Mexico

The National Hurricane Center is issuing advisories on Hurricane Katia located about 1065 miles east of the Leeward Islands.

1. A trough of low pressure located over the central Gulf of Mexico is producing a large area of cloudiness and thunderstorms and gusty winds mainly on its east side. Upper-level winds are currently unfavorable for development. However...conditions are forecast to become more conducive later today and the system could become a tropical depression during the next day or so. This system has a high chance 70% of becoming a tropical cyclone during the next 48 hours as it moves slowly northwestward. Interests along the entire northern Gulf of Mexico coast should monitor the progress of this disturbance.

2. A non-tropical low pressure system is located about 360 miles north of Bermuda. This low is expected to move northeastward at 10 to 15 mph without significant development over the next couple of days.

This system has a low chance 10% of becoming a tropical cyclone during the next 48 hours. Elsewhere...tropical cyclone formation is not expected during the next 48 hours.
