Overview

• Met Office guidance highlights a deep low tracking northeast on Saturday–Sunday with gusts above 50 mph and 10–20 mm of rain for many, with higher totals on hills and coasts.
• Observed downpours already topped 63 mm in parts of Cornwall and more than 50 mm in Devon and Dorset, prompting Environment Agency flood alerts on rising rivers in southeast London and Kent.
• Forecasters expect the UK’s unsettled pattern to persist into early September, while drought status and hosepipe bans remain in several regions despite recent rain.
• The National Weather Service projects 2–4 inches of rain across South Florida through Tuesday with isolated 10+ inch totals possible, raising urban and flash‑flood concerns under a stalled boundary and deep tropical moisture.
• A cold front ushers in a cooler, drier Labor Day weekend for the Northeast and Midwest, with Maine seeing storms Friday before clearing, and cities like New York, Chicago and much of Maryland enjoying sunny 70s and cool nights in the 50s.
