St. Louis, Missouri – Dry air and gusty winds are increasing the risk of fast-moving grass fires across eastern Missouri this afternoon, especially near major corridors like I-44 and I-64 through 7 p.m. Saturday.
According to the National Weather Service in St. Louis, elevated fire danger is expected across most of the region, with the exception of parts of southwestern Illinois. Low humidity and periodic wind gusts could allow flames to spread quickly if a fire ignites.
Across the metro area, including St. Louis County, St. Charles County and Jefferson County, dormant winter vegetation provides ample fuel. Open fields along I-70, I-55 and I-270 are particularly vulnerable where dry grasses line roadways. Even a discarded cigarette or a vehicle parked over dry brush could spark a roadside fire.
Fire officials warn that behavior in these conditions can be unpredictable, especially during the warmest part of the afternoon when humidity dips lowest. Rural stretches and construction zones along I-255 and Highway 40 face added risk due to exposed vegetation.
Residents are urged to avoid outdoor burning and leave any necessary prescribed burns to trained professionals. Properly extinguish cigarettes, secure trailer chains to prevent sparks and avoid parking vehicles on dry grass. Keep water sources nearby if working outdoors with equipment that could produce heat or sparks.
Conditions will gradually improve after sunset as temperatures fall and humidity recovers, but caution remains essential through early evening. Additional statements could be issued if winds increase or fire activity develops across the region.
