Remove clothing, use fans and air conditioners. If temperature rises again, repeat process. Do not give fluids. How does NOAA keep the public informed about heat waves? With the National Weather Service Heat Index Program, the National Weather Service (NWS) has stepped up its efforts to alert more effectively the general public and appropriate authorities to the hazards of heat waves - those prolonged excessive heat/humidity episodes. Based on the latest research findings, the NWS has devised the "Heat Index" (HI), (sometimes referred to as the "apparent temperature"). The HI, given in degrees F, is an accurate measure of how hot it really feels when relative humidity (RH) is added to the actual air temperature. How does the NWS alert the public to the occurrence of a heat wave? The NWS will initiate alert procedures when the HI is expected to exceed 105 degrees to 110 degrees F (depending on local climate) for at least two consecutive days. The procedures are: Include HI values in zone and city forecasts. Issue Special Weather Statements and/or Public Information Statements presenting a detailed discussion of 2. the extent of the hazard including HI values, 3. who is most at risk, 4. safety rules for reducing the risk. Assist state/local health officials in preparing Civil Emergency Messages in severe heat waves. Meteorological information from Special Weather Statements will be included as well as more detailed medical information, advice, and names and telephone numbers of health officials. Who is most susceptible to heat related illnesses? Elderly persons, small children, chronic invalids, those on certain medications or drugs (especially tranquilizers and anticholinergics), and persons with weight and alcohol problems are particularly susceptible to heat reactions, especially during heat waves in areas where a moderate climate usually prevails.
