From the Editor

John Wasserman

Greetings shipmates and friends and welcome once again to the Mariners Weather Log (MWL).

Before I get started with anything, it is my sad duty to report the passing of our Miami PMO, Peggy Alander. Peggy has been battling cancer for the last several years. Her story is detailed on page 29. Please keep Peggy and her family in your thoughts and prayers. When talking to Peggy during her final week, one of her biggest concerns was, who would take care of her ships? She was a fantastic person and an incredible Port Meteorological Officer. It was an honor knowing her. She will be sorely missed!

This issue we welcome aboard two new PMO’s. Rob Niemeyer has taken over the position in Jacksonville, Florida and Peggy Perales in Valdez, Alaska. Their bio’s are on page 30. Please join me in welcoming them aboard. They both bring a great deal of experience to the US VOS program and we are excited to have them aboard.

This issue we are finishing up our 3 part series brought to us courtesy of the Mariners Museum in Newport News, VA. This piece is called "The Great Exchange".

With the sad loss of Peggy, it has been very difficult to get into a "nautical mode". This is not a good sign when the editor of the MWL can't get into nautical mode. So, I have a confession, in order to get my head in the right for this issue, I had to pull out the old Tommy Makem and the Clancy Brothers albums. A few reels and shanty's later, I was ready to edit. If their rendition of "The Irish Rover" does not get you in the nautical mood, nothing will!

Since taking over this position earlier this year, not one week has gone by without several calls for reprinting the article "Mariners Guide to the 500 mb Chart" In this issue we are proud to update this very popular article from the winter of 1995" I strongly recommend that you hold on to this version as a reference, I will make sure that we keep a version of it on the US VOS website. This version of the article is not only updated but is expanded covering more recent charts and concepts. As a companion to this article, you may want to check out "Heavy Weather Avoidance...Concepts and Applications of 500 Mb Charts" by Captain Ma-Li Chen and Lee Chesneau. You can obtain a copy by contacting Lee Chesneau through his website at

Lastly, thank you to all the authors of the articles in the MWL. They are the reason for this magazine success.

Please enjoy and drop me a note anytime.


Twas a wonderful craft,
she was rigged fore and aft
And how the wild winds drove her
She 'stood several blasts, she had twenty-seven masts
And they called her the Irish Rover
