Drenching thunderstorms are in the forecast on Monday. Flooding is expected in the heaviest rain bands Monday morning through the early evening. While most areas will see around an inch of rain, isolated downpours could dump 2 to 3 inches in a short window, quickly triggering problems across local neighborhoods.

Sunday night will remain muggy with temperatures lingering around 70 degrees and a rising chance of late-night showers and scattered thunder. Boaters and beachgoers should stay alert—a Small Craft Advisory for the Atlantic Ocean takes effect at 8 a.m. Monday, alongside a high risk of dangerous rip currents and the threat of early lightning strikes ahead of the rain.

Conditions will briefly improve on Tuesday as clouds break for sun and rain subsides, though high humidity will keep mid-80s temperatures feeling uncomfortable. Hot, muggy weather will then persist through the rest of the week, with daily sun and cloud mix giving way to afternoon scattered thunderstorms and heat indices pushing real-feel temperatures close to 90 degrees.
