- Avoid floodwater: Do not drive thru standing water-just 6 in of moving water can lift most vehicles.
- Prepare emergency kit: Include flashlights,batteries,bottled water,non‑perishable food,and a portable power bank.
- Check evacuation routes: Use the NY.gov “Flood evacuation map” and NJDOT “Road Closure Dashboard” for real‑time detours.
Practical Readiness Checklist (Step‑by‑Step)
- Review your home’s flood risk – Visit FEMA’s Flood Map Service Center and input your address.
- Install battery‑back‑up for sump pumps – Prevent basement flooding if power fails.
- Inspect drainage systems – clear gutters and downspouts of debris before the rain peaks.
- Protect electronics – Elevate routers, smart home hubs, and televisions above potential flood levels.
- Notify neighbors – Coordinate with elderly or disabled residents who may need assistance.

Real‑World example: 2023 Monmouth County Coastal Flood
In October 2023, a comparable storm surge of 2 ft caused $12 million in property damage across Asbury Park and Belmar. Post‑event analysis highlighted three critical lessons:
- Early sandbag deployment reduced roadway flooding by 40 %.
- Community alert apps increased evacuation compliance from 68 % to 92 % when activated 24 hours beforehand.
- Portable generators for shelters ensured continuous power for medical equipment, preventing emergencies.
These insights are being applied to the current advisories, with the Monmouth County Emergency management Agency pre‑positioning sandbags and activating it’s mobile alert system at 10 a.m. today.
How to Stay Informed (Digital Tools)
- National Weather Service (weather.gov) – Live radar, hourly precipitation forecasts, and flood‑watch polygons.
- NOAA Weather Radio – set to receive alerts on frequency 162.55 MHz; portable radios available at most hardware stores.
- Weather‑aware apps: AccuWeather, Dark Sky, and the American Red Cross Flood Alert app provide push notifications for your zip code.
