     EFFECTIVE JULY 10 1996...THE STORM PREDICTION CENTER IN
NORMAN...OKLAHOMA...WILL BEGIN A TEST OF A NEW PRODUCT CALLED THE
HAZARDOUS WEATHER UPDATE.  THESE HAZARDOUS WEATHER UPDATES WILL
PROVIDE FORECASTS /OUT TO APPROXIMATELY 12 HOURS/ OF HAZARDOUS
WEATHER AFFECTING THE CONTIGUOUS UNITED STATES.  THE PURPOSE OF
THE HAZARDOUS WEATHER UPDATE WILL BE TO PROVIDE NATIONAL WEATHER
SERVICE OFFICES...OTHER FEDERAL AND STATE AGENCIES...EMERGENCY
MANAGERS...AND THE MEDIA...WITH AN OVERVIEW OF MAJOR ON-GOING
STORM SYSTEMS AND OTHER HAZARDOUS WEATHER EVENTS THAT HAVE
REGIONAL OR NATIONAL SIGNIFICANCE.  

     THE HAZARDOUS WEATHER UPDATE WILL BE A NON-SCHEDULED
PRODUCT...AND WILL BE ISSUED ONLY WHEN HAZARDOUS WEATHER AFFECTS
MAJOR PORTIONS OF THE COUNTRY.  THE TYPES OF HAZARDOUS WEATHER TO
BE COVERED INCLUDE SEVERE THUNDERSTORMS AND TORNADOES...LOCALLY

     THE HAZARDOUS WEATHER UPDATES WILL APPEAR IN AFOS/NWWS
IDENTIFIERS MKCHWU01 THROUGH MKCHWU09.  FOR WMO/FOS...THESE WILL
ALL BE FOUND UNDER THE HEADER OF WWUS44 KMKC.  HAZARDOUS WEATHER
UPDATES FOR A STORM WILL USE THE SAME AFOS IDENTIFIER FOR THE
LIFE OF THAT STORM.  EACH TIME A SET OF HAZARDOUS WEATHER UPDATES
IS INITIATED FOR A NEW STORM...THE FINAL DIGIT OF THE IDENTIFIER
WILL BE INCREASED FROM THAT OF THE PREVIOUS STORM SYSTEM.  

     THE TEST WILL LAST APPROXIMATELY ELEVEN MONTHS...ENDING
IN MAY 1997.  DURING THAT TIME...FEEDBACK FROM NATIONAL WEATHER
SERVICE OFFICES...EMERGENCY MANAGEMENT...AND THE MEDIA WILL BE
USED TO DETERMINE THE UTILITY AND FORMAT OF THIS PRODUCT.  ONLY
AFTER COMPLETION OF THE TEST WILL IT BE DETERMINED IF THE
HAZARDOUS WEATHER UPDATE IS TO BECOME ONE OF THE SUITE OF
PRODUCTS ISSUED BY THE STORM PREDICTION CENTER.
