county warning area map

The National Weather Service office at Sullivan accepts reports from any county on this map. Before submitting a report you need to learn what's  reportable and what information must be included with every report.

REPORTABLE CRITERIA: Tornadoes, waterspouts, funnel clouds, wall clouds, high winds, large hail, damage, flooding, and rain gage info. See below for details.

INFORMATION: All reports must include Time, Location, Condition, and Source. (T-L-C-S) See below for details

Reports are sent by: Unlisted NWS phone number, some 9-1-1 centers, E-Spotter (internet), NWS websites, the NPOP program, or ham radio channels. Upon becoming familiar with this process, reports can be passed in under 45 seconds.



Later this year the Sullivan NWS will launched a new system called NPOP (National Public Observation Program) that permits the general public with a touchtone phone to submit reports thru a automated voice menu system. To use NPOP the public must know either their Zip code
or Latitude-Longitude. See these links   Zip Code Boundary Link   Lat and Long link Trained spotters should use the E-spotter link or their designated 800 number.
