The Significant Weather Observation Program (SWOP) was created at the National Weather Service in Central Illinois in order to provide forecasters with additional data during and after significant weather events.  Participants in the program provide the NWS with real-time reports; including rain and snowfall amounts, as well as data associated with thunderstorms such as hail size, wind gusts, and flooding.  The information gathered from SWOP observers is used to aid forecasters in the issuance of various statements, advisories, and warnings.

MORE ABOUT SWOP

Training sessions for SWOP members are conducted periodically.  The sessions serve to keep observers up to date and to give National Weather Service staff a chance to personally meet and interact with them.

SWOP members send their weather reports to the National Weather Service via e-mail at nwsliilx@noaa.gov  

Weather Reports from SWOP observers are collected and placed online.  Rain and snowfall totals from across central Illinois are routinely posted.  In addition, after severe weather episodes, event summaries will be compiled and placed online as well.
