All of Delaware has been placed under a severe thunderstorm watch, while Kent County is under a hazardous weather outlook, until around 9 p.m. Monday, according to the National Weather Service.
Storms are expected to rumble into the mid-Atlantic region into the early evening, bringing threats of wind damage, large hail and possibly a few tornadoes.
NWS said an intensifying low-pressure system along a cold front will slice its way through the Eastern seaboard Monday, causing thunderstorms to intensify into a squall line, as they advance east across the Northeast and mid-Atlantic.
Storms within that line — including in Delaware — could produce widespread and damaging straight-line winds.
Trees and power lines could be downed by stronger gusts, and power outages are probable in some areas. The early-evening commute will likely be impacted by this weather.
The threat of severe weather will last through about 8 p.m. Monday, before calmer weather returns overnight.
It is expected to be sunny Tuesday with a high near 77.
