Sussex County and Delaware’s beach communities should expect a warm, humid start Wednesday, followed by an increasing chance of showers and thunderstorms later in the day and into the evening as a cold front moves through.

Strong to severe storms, damaging wind gusts, minor bay flooding and rough marine conditions are expected from late Monday evening into late Tuesday evening in Sussex County and along the Delaware and Maryland beaches.

Today on Delmarva, a powerful storm system will bring the risk of strong to severe thunderstorms this afternoon into tonight, with damaging winds as the primary concern and an increasing threat for isolated tornadoes. Even outside of storms, southerly winds will gust from 35 to 45 mph, with some areas seeing gusts up to 50 mph. Heavy rainfall may lead to localized flash flooding, especially inland, while Sussex County faces minor coastal flooding along the back bays including Rehoboth Bay and Little Assawoman Bay. Conditions turn cooler and dry Tuesday through Wednesday before temperatures gradually moderate later in the week, with the next chance for showers arriving Friday night into Saturday.

Delmarva enjoys one more day of record-setting warmth today, with inland highs in the upper 70s to low 80s and cooler readings near the water. Gusty south winds, higher humidity, and increasing clouds will build through the afternoon before a threat for a few strong to severe storms develops this evening, mainly between 6 and 10 p.m. A strong cold front moves through late tonight into Thursday morning, bringing falling temperatures, gusty northwest winds, and much colder air to end the week.

Spring fever continues across Delmarva as high pressure over the western Atlantic brings sunny skies, highs in the 70s inland, and even a few spots near 80. Beach communities should turn sunnier with highs in the 60s before fog returns tonight. Wednesday will be the last very warm day before a strong cold front arrives with gusty winds and the chance for a few strong to severe thunderstorms Wednesday evening, followed by sharply cooler air.
