Advisory

Red Flag Warning

...RED FLAG WARNING IN EFFECT FROM 10 AM THIS MORNING TO 8 PM CST THIS EVENING FOR WIND AND LOW RELATIVE HUMIDITY...

The National Weather Service in St. Louis has issued a Red Flag Warning for wind and low relative humidity, which is in effect from 10 AM this morning to 8 PM CST this evening.

* TIMING...From 10 AM this morning until 8 PM this evening.

* WINDS...West 10 to 20 mph with gusts up to 35 mph.

* RELATIVE HUMIDITY...As low as 19 percent.

* IMPACTS...These conditions are conducive for the rapid spread and growth of uncontrolled wildfires. Any fires that develop will catch and spread quickly. Outdoor burning is discouraged.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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 dry fuels can contribute to extreme fire behavior.

The Missouri Division of Fire Safety offers these suggestions on how to reduce the spread of fires: 
  • Refrain from any open burning of leaves, brush or debris whenever conditions warrant.
  • Do not wait to call 911 at the first sign of a fire.
  • Smokers should be extremely careful, extinguishing cigarette and cigar butts completely before disposal. Do not discard cigarettes from motor vehicles.
  • Secure trailer chains to prevent dragging. A spark in contact with dry grass could start a fire.
  • Off-Road Driving: Use caution when driving vehicles off-road. Sparks from vehicles or equipment coming in contact with dry grass can start fires in dry conditions. Catalytic converters on motor vehicles can also start fires when they come in contact with fine, dry fuel, such as grass. Always carry a fire extinguisher on vehicles that are used off-road.
  • Grilling: Use caution with outdoor grilling. Position the grill well away from siding, deck railing, and out from under eaves and overhanging branches. Never add charcoal starter fluid when coals or kindling have already been ignited. Never use any flammable or combustible liquid other than charcoal starter fluid to get the fire going. Periodically remove grease or fat buildup in trays below the grill so it cannot be ignited by a hot grill.
  • Fire Pits and Campfires: Be extra careful with fire pits and campfires, exercising the same precautions you would with an open fire. Consider the risks before lighting the fire. If you decide to light a fire, check the wind direction. Keep a fire extinguisher or garden hose nearby. Do not overload. Do not burn trash and leaves. Avoid using soft woods that are likely to pop and throw sparks. Remember to make sure the fire is fully extinguished before leaving the area. Embers in the fire bed can reignite a fire.
