First Warning Forecast

Several rounds of flooding this weekend… Remnants of Sally are pulling away from the east coast with only a few leftover showers today. Going forward, winds will crank up today, NE 15-25 with gusts to 30+ mph. “Minor” level coastal flooding is expected during times of high tide today.

Low rain chances, lower humidity and much cooler this weekend with only isolated rain Saturday and more sunshine Sunday. However, strong NE winds at 15 to 25 mph and gusts to 35+ mph likely to be problematic both Saturday and Sunday. Those persistent NE winds may initiate “moderate” level tidal flooding for multiple high tides.

Strong NE winds likely to drive up another round of tidal flooding Monday. Winds will back down on Tuesday. Expect more sunshine next week with high temperatures warming from the 60s on Monday to the 80s by Thursday.

Today: Mostly Cloudy, Rain, Windy. Highs in the mid 70s. Winds: NE 15-25G35

Tonight: Mostly Cloudy, Isolated Showers, Windy. Lows in the mid 60s. Winds: NE 15-25G35

Tomorrow: Mostly Cloudy, Isolated Showers. Highs in the upper 60s. Winds: NE 15-25G35

Tropical Update

Hurricane Teddy continues to churn over the central Atlantic. It is now a major hurricane with max sustained winds of 130 mph about 525 ENE of the northern Leeward Islands. Teddy is about 885 miles southeast of Bermuda. The powerful category 4 hurricane is moving to the northwest at 12 mph, but it's forecast to turn more northerly Sunday on approach to Bermuda late Sunday into Monday.

Large swells by Teddy are expected to cause rough surf and elevated rip current risk for the U.S. east coast, Leeward Island, the Bahamas and Bermuda. Hurricane force winds extend outward up to 60 miles from the center... tropical storm force winds extend outward by 230 miles.

Tropical Storm Wilfred forms in the eastern Atlantic as the last-named storm on the 2020 Atlantic Hurricane list. It's nowhere near land as it moves WNW AT 17 mph about 630 miles WSW of Cabo Verde Islands. Max sustained winds of 40 mph with higher gusts. It's forecast to strengthen some today, but overall a weakening phase is likely this weekend - it poses no threat.

Tropical Depression #22 sits in the western Gulf of Mexico with a forecast track to the north. However, there's a lot of uncertainty on where it'll go next - either towards Louisiana or the southern Texas coast where there's an increasing threat of heavy rainfall and flooding. Right now, the slow-moving depression to the NNE at 7 mph is close to tropical storm strength with max sustained winds of 35 mph and higher gusts.

The next storm will be named from the Greek Alphabet... Alpha forms offshore of Portugal as a subtropical storm Friday afternoon, but there is absolutely no threat to the United States.
