Tropical Update
A non-tropical low pressure area centered about 450 miles ENE of Bermuda has become better organized during the past several hours. The low has not yet acquired subtropical storm characteristics. If current trends continue advisories could be initiated on the system later today or tonight as it moves west to WSW to the northeast of Bermuda. The low is forecast to move NE into a more hostile environment by Saturday night or Sunday.
* Formation chance through 48 hours: High (90%)
* Formation chance through 5 days: High (90%)

Recent satellite imagery suggests that a low-level circulation is forming over the western Gulf of Mexico. Environmental conditions are expected to be marginally conducive for development, and a short-lived tropical depression or storm could form before the disturbance moves inland over the northwestern Gulf coast tonight.
* Formation chance through 48 hours: Medium (40%)
* Formation chance through 5 days: Medium (40%)
