...RED FLAG WARNING FOR LOW HUMIDITY AND GUSTY WIND WEDNESDAY AFTERNOON AND EVENING IN EASTERN IDAHO... .A dry cold front will approach Idaho from the west on Wednesday. This will have the effect of increasing the wind prior to the arrival of the cold air on Wednesday night. Wednesday afternoon and evening will see the combination of humidity below 15 percent and wind gusts of 25 or 30 mph produce dangerous conditions for areas where this occurs and where fuels are receptive to fire. The National Weather Service in Pocatello has issued a Red Flag Warning for gusty winds and low relative humidity, which is in effect from 3 PM to 9 PM MDT Wednesday. * AFFECTED AREA...Fire Weather Zone 410 Upper Snake River Valley/Idaho Falls BLM and Fire Weather Zone 413 Caribou Range/Caribou NF. * WINDS...Southwest 10 to 20 mph with gusts up to 35 mph. * RELATIVE HUMIDITY...As low as 11 percent. * IMPACTS...When these weather conditions combine with critically dry fuels, extreme fire behavior, including intensity and spread rate, can result.

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.
