Overview
- The Storm Prediction Center placed parts of the Ohio Valley through the Mid‑Atlantic and Northeast at an Enhanced Risk for severe weather, warning Tuesday that organized thunderstorms may produce widespread damaging wind gusts, heavy rain that can cause flash flooding, large hail and isolated tornadoes.
- Tropical Storm Bertha is forecast to bring tropical‑storm conditions to parts of the Gulf Coast while pushing a plume of very moist air northward that is increasing rainfall rates and flood risk across the eastern U.S.
- The Weather Prediction Center and local National Weather Service offices have expanded Major to locally Extreme HeatRisk across the Southern and Central Plains, where heat‑index values may reach 105–115°F and warm overnight lows will worsen cumulative heat stress through the coming week.
- Post‑tropical Elida off Baja is producing dangerous surf along the Northern California coast and has prompted a red‑flag fire‑weather warning for parts of Siskiyou, Humboldt and Trinity counties as forecasters expect coastal thunderstorms and dry fuels to raise conflagration risk.
- India’s southwest monsoon has revived and the India Meteorological Department has issued widespread rain alerts with heavy to extremely heavy downpours that have already caused deadly floods and landslides in Jammu and Kashmir and prompted multiple state warnings and suspended pilgrimages.
