Red Flag Warning issued May 20 at 3:18AM CDT until May 20 at 9:00PM CDT by NWS Duluth MN

Effective: Tue May 20, 2025, 3:18 AM
Expires: Tue May 20, 2025, 9:00 PM

...RED FLAG WARNING IN EFFECT TODAY MAY 20 FOR CRITICAL FIRE WEATHER... A strong high pressure system over Ontario will bring an area of very dry air to northern Minnesota, along with a tight pressure gradient that will make for strong east winds. Relative humidity may drop as low as 15 to 20%, with east winds of 15 to 25 mph, with gusts as high as 40 mph. Across eastern portions of the Red Flag Warning, a Wind Advisory is also in effect. The National Weather Service in Duluth has issued a Red Flag Warning for wind and low relative humidity, which is in effect from noon today to 9 PM CDT this evening. The Fire Weather Watch is no longer in effect. * AFFECTED AREA...In Minnesota, Koochiching, North St. Louis, Northern Cook and Lake, North Itasca, Central St. Louis and South Itasca. * WINDS...East 15 to 20 mph with gusts up to 40 mph. * RELATIVE HUMIDITY...As low as 15 percent. * IMPACTS...Any fires that ignite could spread rapidly and become difficult to control. 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.
