Strong low pressure will bring very strong winds and blizzard conditions to portions of the Northern Plains into Monday. Winds gusting over 60 mph at times may cause whiteout conditions. A second low pressure system is forecast to intensify rapidly off the U.S east coast bringing strong winds, heavy rainfall, and coastal flooding to the Carolina's. Heavy snow will impact eastern New England.
Tropical cyclone products issued by the National Hurricane Center (NHC) are located on the NHC website at www.hurricanes.gov. Complete advisories are always issued every six hours for an active storm at these times: 5a, 11a, 5p and 11p EDT.
Automatic alerts are available directly from NHC when a new tropical cyclone advisory is issued by following NHC on Twitter @NHC_Atlantic and @NHC_Pacific . (See the Twitter entry at weather.gov/subscribe for a link to instructions for how to set up SMS alerts from our Twitter feed.) Additional sources of both email and texts alerts are identified at weather.gov/subscribe.
Information Specific to Mariners
Options which provide low bandwidth email delivery of weather information include email listservers (e.g., University of Illinois Listserver, ACEMWIN-HURR-L Hurricane Bulletins Listgroup), SAILDOCS, and FTPMAIL which are all documented at http://weather.noaa.gov/pub/fax/robots.txt and weather.gov/subscribe.
Listservers works well for low-bandwidth delivery of hurricane information. The SAILDOCS subscription only lasts 2 weeks before requiring renewal and FTPMAIL requires a request each time. Both SAILDOCS and FTPMAIL also require management (i.e., specific requests) to get desired products (e.g., TCMs, etc.) for only active storms.
For convenience, the directions for obtaining Atlantic Outlooks and Tropical Cyclone Forecast/Advisories (TCM) via the Illinois Listserver are provided below. For more complete directions and available products see http://weather.noaa.gov/pub/fax/uiuclist.txt (for the Pacific, WX-TROPL vs. WX-ATLAN is used).
