  • Heavy rainfall and flash flooding threaten Florida and Gulf Coast as Invest 93L moves westward

    A low-pressure system designated Invest 93L is moving westward across the Florida Peninsula on July 15, 2025, with a medium chance of tropical cyclone development in the northeastern Gulf by mid-week.

  • Flash flooding expected in Mid‑Atlantic and Florida due to record moisture and slow-moving storms

    Flash flood potential is elevated across several U.S. regions, with a Moderate Risk (level 3/4) in effect for the I-95 corridor in the Mid‑Atlantic from July 14 into July 15, 2025, due to a slow-moving frontal boundary and record-setting atmospheric moisture. Elevated flash flood risk also exists across the Florida Peninsula as deep tropical moisture and slow-moving storms impact the region.
