4/01/2014          Draft FAQs  posted

We have now begun to circulate a FAQ for how to use the new forecasts, and what is expected from the team that is working towards an official launch on Dec 1, 2014. Have a boo here and please add your comments.

3/25/2014          Saildocs begins distributing experimental forecasts

Jim Corenman has implemented the codework so that you can begin receiving the new forecasts.  How to do it is here.

3/19/2014          NOAA briefing note

Southbound Evening Net recently provided a briefing note to the National Hurricane Center. The purpose of the note was to give a bit of a sense of “cruiser behaviors” on the West Coast of Mexico and south, especially regarding where they go and why during the cruising season.  It can be found here.

Below is a chronological list of updates on this NOAA project.  Please let me know if there is anything you’d like to add, or complain about. As of  March 17,  the developers were hopeful that a stream of “experimental” forecasts would be ready for distribution by SailDocs. Once that process is underway it will be announced here.

In the interim,  they will be available on this website in an unedited manner.

3/18/2014          Some sample forecasts   here.

3/17/2014          Distribution by Saildocs by end of March  here.

2/4/2014           NOAA to launch new forecast service for coastal  Eastern Pacific

The Southbound Evening Net has been in contact with NOAA for several weeks now to see if cruisers in this area of the world can access more detailed coastal forecasts than have been available up til now.  And the news is quite promising.

Starting (hopefully) and the end of February, 2014, the federal agency will be launching a trial period of a new forecasting service that covers the East Pacific coastline from San Diego to Ecuador.

NOAA’s new proposed Offshore Waters Forecast will  provide a detailed 5 day forecast.

“We plan on going from near the coast out to 250 NM from the Mexico/California border all the way to Ecuador (including 2 zones in the Sea of Cortez/Gulf of California), broken up in to about a dozen or so “zones” total based on climatology, political boundaries, jump points, etc.”

“The 5 day forecast will be broken down in to 12 hour forecast periods for the first 60 hours, then in to 24 hour forecast periods for Days 3-5.  At a minimum we will provide A range of Winds (e.g. NW to N Winds 10 to 15 KT) and Seas (e.g. Seas 3 to 5 FT building to 4 to 6 FT late), and weather conditions (e.g. Scattered Showers and Isolated Thunderstorms).  There are plans to provide more detailed wave information (swell directions, wave periods, etc.).”

If you are interested in participating in the trial, please fill out the contact form below. NOAA wants to receive feedback during the trial period in order to fine tune the zones and make it useful to mariners.
