What residents should do now
Prepare for sudden heavy rain and strong winds. Secure outdoor furniture and loose items that could become projectiles. Motorists should be cautious of flooded roadways and reduced visibility during downpours; never drive through standing water. If you have outdoor plans Sunday afternoon or evening, consider moving them indoors or postponing.
Keep a way to receive weather alerts—phone notifications, local TV or radio—and monitor updates from the National Weather Service and local meteorologists as the situation evolves.
Conditions should trend drier and warmer by midweek, with sunnier days expected Thursday and beyond, but residents should remain alert through Monday while multiple rounds of storms are possible.
