Special Weather Statement issued March 21 at 8:43AM CDT by NWS Des Moines IA

Effective: Sat March 21, 2026, 8:43 AM
Expires: Sat March 21, 2026, 3:00 PM

Near record warmth will lead to very low relative humidity today, with minimum values falling to 15-20% this afternoon. Meanwhile, winds will become southwesterly and increase to around 15 MPH with gusts to near 25 MPH at times. Most surface fuels remain cured and dry and any fires that start may spread quickly. Burning is discouraged today.


Red Flag Warning issued March 21 at 9:44AM CDT until March 21 at 10:00PM CDT by NWS Des Moines IA

Effective: Sat March 21, 2026, 9:44 AM
Expires: Sat March 21, 2026, 5:45 PM

...Critical Fire Weather Conditions Today... .While winds will not be overly strong today, near record to record temperatures, cured surface fuels, and exceptionally dry air for Iowa will lead to a critical fire weather danger through this evening. Fires will have a higher likelihood of igniting in these dry conditions and will easily spread, perhaps rapidly at times. Outdoor burning is strongly discouraged. * AFFECTED AREA...Southwest and West Central Iowa into parts of Central Iowa. * WIND...From the southwest at 10 to 20 mph with gusts of 20 to 25 mph. * HUMIDITY...As low as around 15%. * IMPACTS...Any fires that develop will likely spread, perhaps rapidly. Outdoor burning is not recommended.

A Red Flag Warning means that critical fire weather conditions are either occurring now, or will shortly. A combination of strong winds, low relative humidity, and warm temperatures can contribute to extreme fire behavior.

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.
