WHAT IS SWOP?

Training   Weather Reports    FAQ   Links

     The Significant Weather Observing 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 data gathered from SWOP observers is used to aid forecasters in the issuance of various statements, advisories, and warnings.

JOINING SWOP

     If you would like to become a participant in the SWOP program, send an e-mail to nwsliilx@noaa.gov , and we will get back to you as soon as possible.  In order to be part of SWOP, you will need to have access to a computer.   Please include the following information in your e-mail:

1. Full Name and Address (including county)

2. Home Phone Number

3. Preferred e-mail address

     Training sessions for SWOP members are usually conducted twice per year.  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 in one of two ways: either through a web-based report form or through e-mail.  We highly encourage use of the web form, since that is the quickest way to get data to us.  Participants may also send reports through the SWOP e-mail account 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.
