Special Weather Statement issued March 30 at 9:17AM CDT by NWS Quad Cities IA IL

Effective: Mon March 30, 2026, 9:17 AM
Expires: Mon March 30, 2026, 5:30 PM

Gusty south to southwest winds gusting up to 25 to 30 MPH will combine with near record warn temperatures, low humidity, and plentiful dried vegetation to produce an Elevated Fire Danger through early this evening. If a fire were to start under these conditions, there would be an increased threat of fire spread and be difficult to control. Outdoor burning is strongly discouraged. Use extra caution while operating outdoor equipment around dry vegetation and do not carelessly discard cigarettes.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
