If you have information about recent weather impacts in your area or photos of flooding, hail, spinning tornadic clouds, washed-out roadways or culverts, or uprooted/damaged trees, please use the green button to let us know.  You can even send us a photo! 

EM uses the data you share to verify severe weather forecasts from the National Weather Service and automatically sends road damage information to the Public Works Department so they can take action quickly to ensure public safety.

Our Preparedness Guide contains information about local hazards, things residents can do to get prepared, a map of evacuation zones, and important phone numbers.
