Effective Tuesday, April 2, 2013 at 200 PM Eastern Daylight Time (EDT) or 1800 Coordinated Universal Time (UTC), the National Weather Service Forecast Office (WFO) in Key West, Florida will adjust its current coastal waters zones for the Florida Keys.  This adjustment will provide improved marine weather warning and forecast services for portions of the Gulf of Mexico and Barnes Sound.

GMZ033 and GMZ034 will be expanded northward to latitude 25 degrees north; GMZ032 will be split, with GMZ035 added north of the lower Florida Keys; and Barnes Sound will be transferred from AMZ630 to GMZ031.
