Beware of hypothermia during these cooler months. Did you know your body can cool 25 times faster in water than in air? That water does not need to be very cold to endanger you?

What is a "Marine Zone Forecast"?
What is a "Marine Point Forecast"?

How can I get a marine forecast via zip, city, or lat/lon?

Did you know that the height of some individual waves may be twice the height of the forecast seas? And may present an even greater danger near shore or any shallow waters?


Radar Product Central Collection/Distribution Service (RPCCDS)

Next Generation Weather Radar (NEXRAD) makes conventional reflectivity observations and also uses the "Doppler effect" to measure motion of clear air and atmospheric phenomena within storms. The maximum range of NEXRAD is 230 kilometers (125 nautical miles). Although NEXRAD is land-based, there is some radar coverage offshore. The greatest offshore coverage is along the Atlantic and Gulf coasts.

External NEXRAD Radar data users can receive products through the Radar Product Central Collection/Distribution Service (RPCCDS) by a variety of means. Visit the RPCCDS Webpage for further details.

NEXRAD Doppler Radar images are available on the Internet from the NWS Homepage and local NWS Forecast Offices.

For information on displaying NEXRAD Doppler radar in GIS software, Cick here.

An archive of NEXRAD data is available at the National Center for Environmental Information.
