As the wind increases, heat is removed from a body at an accelerated rate, driving down the body temperature. The wind chill index is the approximate temperature it "feels" to the body if the wind was calm. (Jump to the <a href="../appendix/wchill.htm">Wind Chill Chart</a>.) It is headlined <b>URGENT - WINTER WEATHER MESSAGE</b> and is issued as a Non-Preciptiation Weather Advisory (NPW). <br><br> <h4>Example</h4> <div align="center"><table width="430" cellspacing="0" cellpadding="5" border="1" bgcolor="#ffffcc"> <tr> <td><pre> FTWNPWFTW TTAAOO KFTW 150730 TXZO91>095-101>107-115>122-160000- URGENT - WINTER WEATHER MESSAGE NATIONAL WEATHER SERVICE FORT WORTH TX 130 AM CST WED DEC 15 1999 ...AN ADVISORY FOR DANGEROUS WIND CHILL IS IN EFFECT FOR NORTH TEXAS TODAY...
