Official NWS instructions
Turn around, don’t drown when encountering flooded roads. Most flood
deaths occur in vehicles.
Be especially cautious at night when it is harder to recognize the
dangers of flooding.
Stay safe tonight
Turn around, don’t drown. Most flood deaths happen in vehicles — never drive through flooded roadways; six inches of moving water can knock you down, twelve inches can carry a car.
If water enters the home: stay out of standing water where electricity may be present, avoid the basement until water recedes and power is confirmed off, photograph everything before cleanup (documentation matters for insurance), then call a local restoration contractor — water left sitting starts a second wave of damage within a day.
What this means for restoration teams
Translate this warning into job tickets: interior water intrusion through doors, windows, and foundation seepage; saturated carpet and pad; drywall wicking that shows up as a waterline hours later; and mold risk within 24–48 hours wherever porous materials stayed wet. Low-lying areas and urban drainage failures also bring sewage backup calls — the highest-margin, highest-urgency work.
The play: stage extraction and drying equipment now, pre-position dehumidifiers and air movers, keep an on-call rotation through the morning, and capture address, water source, and affected areas on the first call. Field discipline: photo-document before mitigation, moisture-map every affected room, and get the homeowner’s payment responsibility clear in writing before work starts.
FEMA & federal assistance
If the damage is severe, the FEMA Helpline is 1-800-621-3362 (7 a.m.–10 p.m. local, 7 days). Apply at DisasterAssistance.gov, through the FEMA app, or find a recovery center at fema.gov/drc. Basic eligibility: citizenship or qualified status, identity verification, proof of occupancy or ownership, and unmet needs not covered by insurance. Apply as soon as it’s safe.
Looking ahead
When this warning expires, the danger is not automatically over. Creeks and small streams can crest hours after the rain stops, and additional rounds of storms can re-trigger warnings. Watch for NWS updates overnight. For restoration contractors: water-intrusion calls typically start within hours of water receding and keep coming for days as homeowners discover damage behind walls and under flooring.
