...On-Site Incident Weather Support is Available...

In some cases, on-site weather support can be provided at EOCs and Incident Command Posts. During large and prolonged incidents, the NWS Office in Nashville can dispatch an on-site meteorologist to provide critical wind, temperature, relative humidity, precipitation and dispersion forecasts. These on-site meteorologists are trained in the National Incident Management System (NIMS) and can deploy weather equipment at the incident location, download model and weather data on-site, and provide critical weather briefings to the command team.

Emergency Managers or other Public Safety Officials wishing to request on-site weather support during an incident, or just wanting to learn more about the on-site weather support program, should call the NWS office in Old Hickory, TN. is the U.S. government's official web portal to all federal, state and local government web resources and services.
