Heat Index National Weather Service Heat Index Chart Vrogue Co The red area without numbers indicates extreme danger. the national weather service will initiate alert procedures when the heat index is expected to exceed 105° 110°f (depending on local climate) for at least 2 consecutive days. nws also offers a heat index chart for areas with high heat but low relative humidity. since heat index values. 90 105°f. (32 41°c) sunstroke, muscle cramps, and or heat exhaustion possible with prolonged exposure and or physical activity. caution. 80 90°f. (27 32°c) fatigue possible with prolonged exposure and or physical activity. chart provided by nws tulsa.

National Weather Service Heat Index Chart The ‘heat index’ is a measure of how hot weather "feels" to the body. this table uses relative humidity and air temperature to produce the "apparent temperature" or the temperature the body "feels". these values are for shady locations only. exposure to full sunshine can increase heat index values by up to 15°f. also, strong winds,. Relative humidity. %. heat index =. * please note: the heat index calculation may produce meaningless results for temperatures and dew points outside of the range depicted on the heat index chart linked below. heat index chart and explanation. wpc heat index forecasts. more meteorological conversions and calculations. The heat index is based on work by r.g. steadman and published in 1979 under the title "the assessment of sultriness, parts 1 and 2." in this work, steadman constructed a table which uses relative humidity and dry bulb temperature to produce the "apparent temperature" or the temperature the body "feels". we use this table to provide you with. Classification heat index apparent temperature. general affect on people in high risk groups. ely≥130°fhotvery hot 105°f 129°funlike the “relative” in relative humidity, dew points represent an absolute value of moisture and, as such, are. better measure of atmospheric conditions. the dew point is the temperature, at which if the air.

The heat index equation the computation of the heat index is a refinement of a result obtained by multiple regression analysis carried out by lans p. rothfusz and described in a 1990 national weather service (nws) technical attachment (sr 90 23). In simplest terms, the heat index is the "feels like" temperature, or how hot it really feels when the relative humidity is factored in with the actual air temperature. the heat index is forecast.
