ACROSS THE 3-STATE AREA...
  • WEATHER IN SPACE?       Although outer space has none of the ingredients we usually think of for weather (moisture and temperatures to sustain life), it can still be a stormy place. The source of the storminess is our sun. The sun, like all active stars, is constantly in motion and often produces eruptions of gas and high energy particles into space (sort of like solar burps). Although solar particles continuously bombard the earth, during a solar eruption the"storm"of particles can be particularly intense. These storms can disrupt communication satellites and power grids on the ground. NOAA's Space Weather Prediction Center monitors and forecasts solar activity so that the effects of solar storms can be mitigated. To learn more about space weather, check out: SPACE WEATHER at http://www.swpc.noaa.gov/.


  • FORECASTING: TODAY & YESTERDAY!       (from Kevin Shaw, ACON DC/MD/DE) - Pretty good, cmpreehensive article on forecasting today and yesterday, looking in at NCEP and NCAR, supercomputers, and other great stuff... http://www.nytimes.com/2012/09/09/magazine/the-weatherman-is-not-a-moron.html?pagewanted=5&_r=1


  • NOAA WEATHER RADIO ALL HAZARDS (NWR)       NOAA WEATHER RADIO ALL HAZARDS (NWR) IS A NATIONWIDE NETWORK OF RADIO STATIONS BROADCASTING CONTINUOUS WEATHER INFORMATION DIRECTLY FROM THE NEAREST NATIONAL WEATHER SERVICE OFFICE. NWR BROADCASTS OFFICIAL WEATHER SERVICE WARNINGS, WATCHES, FORECASTS AND OTHER HAZARD INFORMATION 24 HOURS A DAY, 7 DAYS A WEEK. WORKING WITH THE FEDERAL COMMUNICATION COMMISSION'S (FCC) EMERGENCY ALERT SYSTEM , NWR IS AN "ALL HAZARDS" RADIO NETWORK, MAKING IT YOUR SINGLE SOURCE FOR COMPREHENSIVE WEATHER AND EMERGENCY INFORMATION. IN CONJUNCTION WITH FEDERAL, STATE, AND LOCAL EMERGENCY MANAGERS AND OTHER PUBLIC OFFICIALS, NWR ALSO BROADCASTS WARNING AND POST-EVENT INFORMATION FOR ALL TYPES OF HAZARDS ¤ INCLUDING NATURAL (SUCH AS EARTHQUAKES OR AVALANCHES), ENVIRONMENTAL (SUCH AS CHEMICAL RELEASES OR OIL SPILLS), AND PUBLIC SAFETY (SUCH AS AMBER ALERTS OR 911 TELEPHONE OUTAGES). KNOWN AS THE "VOICE OF NOAA'S NATIONAL WEATHER SERVICE," NWR IS PROVIDED AS A PUBLIC SERVICE BY THE NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION (NOAA), PART OF THE DEPARTMENT OF COMMERCE. NWR INCLUDES MORE THAN 985 TRANSMITTERS , COVERING ALL 50 STATES, ADJACENT COASTAL WATERS, PUERTO RICO, THE U.S. VIRGIN ISLANDS, AND THE U.S. PACIFIC TERRITORIES. NWR REQUIRES A SPECIAL RADIO RECEIVER OR SCANNER CAPABLE OF PICKING UP THE SIGNAL.
