  1. Being an OCONUS office in a CONUS world…Weather Hazards of our “Tropical Paradise” • Waterspouts • Mudslides (Debris Flows) • Hurricanes • Frequent thunderstorms • Flash flooding during the wet months (April-December) with no month immune • Possibility of deadly tsunamis which have occurred in the last 100 years • Rip Currents and Large Swells that claim swimmers every year The National Weather Service is an agency under the National Oceanic and Atmospheric Administration, which is a part of the Department of Commerce. The mission of the National Weather Service is to provide weather forecasts and hazardous weather warnings to the public. We maintain a constant eye on the weather across the country 24 hours a day, 7 days a week, 365 days a year. A staff of over 4,500 skilled employees accomplish this mission with the assistance of high-speed computer networks, an orbiting fleet of weather satellites in space, and ground-based radar systems. The San Juan forecast office is staffed 24 hours a day with at least one meteorologist and one hydro-meteorological technician.

  3. Being an OCONUS office in a CONUS world…Data Sources/NOAA All Hazards Radio • Radiosonde release twice daily at our local office • One FAA owned Doppler Radar in the mountains of Cayey and a Terminal Doppler Weather Radar (TDWR) at Punta Salinas • ASOS in San Juan, Roosevelt Roads, St Thomas and St Croix • Model data includes a High Resolution model run from NCEP, and locally generated 5 km WS-Eta run, but many CONUS model domains slice through our county warning area. • Very data sparse region…very few buoys, and few observations over the ocean. • Need to transmit both English and Spanish Products on the NOAA All Hazards Radio and out to the public which creates an extremely long Cycle time (over 40 minutes at times) due to necessity to transmit in both English and Spanish • Do NOT have dual transmitters, one for English and one for Spanish • Need to modify all NWR programs to account for Spanish Translations including CAFÉ and NWRWaves • Watches and Warnings need to be done manually by HMT’s/Interns in order to avoid double alarms (Eng then Spn) interrupting radio and TV shows.

  4. Advanced Hydrologic Prediction Service (AHPS)

  5. 3 radiosondes per day (one more than routinely done), but limited to 5 to 6 days • We must receive advance notice to know when we must do a special release • SAL • Dust Forecast • Routine Weather Discussion on SJU web page http://www.srh.noaa.gov/productview.php?pil=SJUAFDSJU&version=0ust Forecast • MODIS Rapid Response System (near realtime images, or look in gallery to browse images • http://rapidfire.sci.gsfc.nasa.gov/subsets • http://rapidfire.sci.gsfc.nasa.gov/gallery
