As for the tropics, Humberto is now a MAJOR Category 4 Hurricane and may likely become a Category 5 by Saturday. Models keep it from making landfall, but there is another area of interest that is likely to become Imelda and will likely have a significant impact next week in the Carolinas.

It may be a strong tropical storm or low-end hurricane, but either way, it will be the first named storm to make landfall during the 2025 hurricane season.
The overall forecast calls for a strong and cool high-pressure cell heading down from the north over our area, cooling us off dramatically by Wednesday but also providing the blocking needed to keep that rain out of our area for a while.

CBS News Philadelphia
It’s still too early to tell, but this storm bears serious watching. If the high doesn’t work in, we could be talking about widespread rain next week around the Delaware Valley.
