We want your input!

Please take a minute to click the survey link below and let us know about disaster preparedness and hazard mitigation from your perspective.  You can even let us know about flood-prone roads and other issues in your neighborhood.  Thank you!

If you have information about recent weather impacts in your area or photos of flooding, hail, spinning tornadic clouds, washed-out roadways, or uprooted or damaged trees, please use the button below to let us know! 

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