USS Vandenberg Forecast to Encounter Gale Force Winds

The USS Vandenberg is underway and on its way to Key West. Hooray!

NOAA is providing daily updates of the ships progress, route, and weather conditions.
According to the video weather forecast, the ship will encounter a developing low pressure system that will create gale force winds today and tonight, with 25-35 knot winds and seas building to 8-15 feet.

Here is the latest NOAA briefing, published yesterday (a new one will be released later today):

With building winds and seas, one has to wonder about that one tug, named Elsbeth III, towing the massive 524' former U.S. Air Force missile tracking ship.
