ALT Key Messages for Considerable Flooding in the Central Plains and Ozarks

ALT A Moderate Risk of Excessive Rainfall is in effect for Saturday across eastern Kansas to central Missouri. A couple of rounds of storms capable of producing torrential rainfall are likely ahead of a system moving into the area. Saturated soils will also enhance the flood risk.

ALT The National Weather Service (NWS) Heat Index Chart. A large grid crosses air temperature (80°F to 110°F on the top horizontal axis) with relative humidity (40% to 100% on the left vertical axis) to calculate the "apparent temperature" or how hot it feels. The background is a color gradient that shifts from yellow on the top-left to deep red on the bottom-right as heat and humidity rise. For example, at 90°F and 70% humidity, the heat index is 106°F. Text on the right reads: "The Heat Index measures how hot it actually feels outside. The Heat Index level that is considered dangerous can vary by person and region." Fine print at the bottom states: "The Heat Index is a product of NOAA’s National Weather Service (NWS)."

ALT Storm Safety during outdoor events: Move to a fully-enclosed structure or hard-top vehicle at the first sign of lightning. Wait 30 minutes after the last strike before resuming activities. Watch for falling debris and flying objects during high winds. Use caution when walking on wet surfaces to avoid dangerous slips and falls. When Thunder Roars, Go Indoors!
