Tropical Storm Andrea Update

(Brevard County, Fla.) - Current Situation Tropical Storm Andrea will reach landfall in/near Apalachee Bay late this afternoon or early evening, then move faster to the northeast into southeast Georgia tonight. As landfall is approached, the most favorable tornado environment will lift north of central Florida. However, the possibility of a trailing rainband may prolong the heavy rain threat for a portion of central Florida.

Tornado WATCH continues for all of east-central Florida (except Volusia County) until 1100 am. The Tornado WATCH will likely be extended for most/all of east-central Florida from late morning into early evening (likely including Volusia County) as wind shear remains favorable for isolated tornadoes and the second rainband moves into the region. Tornado WARNINGS can be issued at any time if radar indicates strong, persistent rotation above ground level.

Projected Impacts

TODAY

·         Lake Wind Advisory in effect for south winds sustained 15-20 mph with gusts 30-35 mph, mainly during times of heavier rain.

·         Scattered showers/storms, along with an isolated tornado threat will continue this morning into mid day, then a stronger rainband with more widespread rain and a greater tornado threat will likely reach the area from around mid day into the afternoon, and may persist into the early evening. 

·         Additional rainfall of 1-3 inches likely, with isolated totals of 3-5 inches, may produce minor flooding. Moderate flooding may occur in a few spots where heavy rains persist.

·         Conditions remain favorable for isolated tornadoes, especially when the next rainband moves into the region this afternoon through early evening.

TONIGHT

·         The most favorable tornado environment is expected to lift north of the region by early evening.

·         Scattered showers and isolated storms may persist well into the evening.

·         One area of concern is the possibility of a rainband trailing south from the Tropical Storm which may persist across a portion of east-central Florida overnight and into early Friday. If this pattern sets-up, a narrow zone of training showers/storms would locally increase the flood threat.

FRIDAY

·         Scattered heavy showers/storms will develop, especially after daytime heating takes place. Typical of the summer, afternoon weather pattern.
