Overview
- Rounds of strong to severe thunderstorms are expected Wednesday through Friday across the Northeast, Mid‑Atlantic, Great Lakes and nearby areas with the main hazards being damaging wind gusts, large hail, heavy downpours and isolated tornadoes.
- Storms have already caused thousands of outages and downed trees in parts of the Northeast and flash‑flooding reports are occurring where heavy rain fell during recent storm clusters.
- Heat advisories cover wide areas with heat‑index readings near 100°F in several regions, creating heightened risk of heat‑related illness for people working or spending prolonged time outdoors.
- Tropical Storm Edouard made landfall near the Texas‑Louisiana border on Tuesday and is producing heavy rainfall and flood watches across southeastern Texas and southwestern Louisiana.
- A developing system near Baja expected to become Hurricane Marie is being watched for the holiday weekend because its tropical moisture and south‑facing swells could increase coastal surf, rip currents and rain chances for Southern and Central California, though the exact track and impacts remain uncertain.
