HURRICANE FREQUENCIES (Unless otherwise noted, times are UTC, freq in kHz) Revised August 1, 1996 The following high-frequency hurricane season intercepts have been gleaned from numerous sources. Times and frequencies are subject to frequent change, and are listed for reference only. Beginning this issue, the list is a collaboration between Bill Snyder of California and Roger Pettengill of New York. This list has been published monthly during hurricane season since 1991. If you copy this list, credit the authors. Do not remove update request and e-mail addresses. This is the only way we can keep the list updated! Thank you all who have so generously contributed information. Enjoy!

Best frequencies to monitor are those guarded by MacDill and Ascension. After initial contact on one of the published GHFS frequencies, listen closely for them to switch to a non-published frequency to pass traffic. Aircraft call signs are "GULL-nn" or "TEAL-nn" (where nn is a 2-digit number), and "NOAA-42" and "NOAA-43." The GULL and TEAL aircraft are type WC-130 based at Keesler AFB, Biloxi, MS. The NOAA aircraft are type WP-3D based at MacDill AFB, Tampa, FL. Look for the new NOAA Gulfstream IV-SP (tail number N49RF, call sign "NOAA-49") to make its debut this season. --------------------------------------------------------------------------- Whenever a hurricane is within 300 miles of land in the northern western hemisphere, the Hurricane Watch Net is operational on 14325. The Hurricane Watch Net provides communication between the National Hurricane Center and the affected areas. --------------------------------------------------------------------------- During a communications emergency, W1AW transmits special bulletins by voice at hh:00, teleprinter at hh:15, and CW at hh:30ncies are: Voice 01855 03990 07290 14290 18160 21390 28590 Teleprinter 03625 07095 14095 18102.5 21095 28095 CW 01818 03581.5 07047.5 14047.5 18097.5 21067.5 28067.5 --------------------------------------------------------------------------- The National Institute of Standards and Technology broadcasts storm warn- ings on 2.5, 5, 10, 15 & 20 MHz AM according to the following schedule: WWV hh:08 Covers Atlantic and eastern North Pacific WWVH hh:48 Covers Western, Eastern, Southern, and North Pacific --------------------------------------------------------------------------- Globe Wireless broadcasts weather information, forecasts and bulletins in CW and SITOR modes on the following time-slot schedule: STATIONS WNU New Orleans, Louisiana VCT Tors Cove, Newfoundland KFS Palo Alto, California FREQUENCIES WNU FEC: 04210.5 06327.0 08425.5 12588.5 12607.5 16384.5 VCT FEC: 04217.5 06329.5 08422.0 12610.5 16827.5 KFS FEC: 04211.5 06315.5 08417.5 12580.5 16829.5 22377.5 WNU CW: 00478.0 04310.0 08570.0 12826.5 17117.6 22575.5 KFS CW: 00476.0 08558.4 12844.5 17026.0 22581.5 FEC PRODUCT & TRANSMISSION TIMES WNU: GOM/CARIB/ATL CYCLO BULL 0220 0520 0820 1120 1420 1720 2020 2320 WNU: GOM/CARIB OFFSHORE FCST 0350 0950 1550 2150 VCT: N ATL HIGH SEAS WX 0450 1050 1650 2250 KFS: E & CTL PAC CYCLO BULL 0220 0520 0820 1120 1420 1720 2020 2320 KFS: PAC HIGH SEAS WX 0450 1050 1650 2CW PRODUCT & TRANSMISSION TIMES WNU: GOM/CARIB/N ATL HSEAS WX 0350 0950 1550 2150 KFS: PACIFIC H SEAS WX 0450 1050 1650 2250 NOTES: 1.

Normal hurricane season extends 01 June to 30 November --------------------------------------------------------------------------- One of the most intere hurricane sites for the technically inclined is the Atlantic Tropical Weather Center page. It is maintained by Eric Blake, an atmospheric sciences major at Northeast Louisiana University. URL is http://banzai.neosoft.com/citylink/blake/tropical.html. Many of the products referenced in this bulletin can be accessed from his site, including weather forecasts, hurricane reconnaissance flight data, satellite weather images, and more. This site links to a boggling array of raw data and information. --------------------------------------------------------------------------- You really can help keep this list current by sharing your additions, cor- rections and deletions.
