NOAA Weather Radio All Hazards (NWR) is a nationwide network of radio stations broadcasting continuous weather information directly from the nearest National Weather Service office. Here is why it is an essential investment for your home:

✅24/7 Direct Alerts: It provides continuous weather information and immediate alerts for watches and warnings directly from your local National Weather Service office.

✅Reliable During Outages: Because they can run on battery, solar, or hand-crank power, they provide a way to stay informed even if the power grid, internet, or cell towers fail.

✅Nighttime Protection: Most radio brands feature a loud tone alert that will wake you up during nighttime threats like tornadoes and flash flooding, giving you crucial seconds to seek shelter.

Don’t be a statistic. Take this moment and:
🛑 STOP what you're doing
📱 CHECK your phone's notification settings
✅ TURN WEAs ON today
It only takes a minute, and it could save your life.

Flash floods can strike in minutes, and relying on just ONE way to get alerts is a risky gamble. Cell networks can drop, phones can lose battery, or you might simply be asleep. Protect yourself and your family with multiple overlapping layers of ways to receive flood/flash flood alerts:

✅ Wireless Emegency Alerts (WEA) enabled on your phone and phone fully charged
✅ NOAA Weather Radio with a battery backup incase of power outages
✅ Local TV & Radio broadcasts
✅ Trusted Weather Apps with push notifications
✅ Contact local Office of Emergency Management to opt-in for local alerting networks
❌ Outdoor sirens are for the outdoors! Don’t rely on them indoors

Scattered afternoon showers and thunderstorms are on tap for today. For this weekend, expect multiple rounds of showers and thunderstorms, some of which could produce heavy downpours and result in flooding in urban areas and areas with poor drainage.

Now let’s discuss what to do in the aftermath of a flood event.

Listen to authorities to stay up to date on road conditions, the safety of drinking water, and the status of electricity outages (if applicable).

There are hidden dangers in the aftermath of floods too! Remnant floodwater can contain debris, toxins, and chemicals. Electrical equipment in the water could result in electrocution. Wait until the all-clear is given before returning to previously flooded areas.

Just because the rain has stopped doesn’t mean that all of the roads will be passable. Avoid driving into floodwaters and remember that it only takes a foot of water to carry away a car. Turn around, don’t drown.

Be sure to check on your neighbors and others in your community following a flood to see if they need any assistance. Check for damage and gas leaks. Do not attempt to move structural supports or large debris.
