Storms off the southern coast

I’ve been watching the storms off the southern coast for the past few hours now. I have an image of a very nice line that was working its way across the gulf earlier tonight. Here’s a shot from WeatherTAP’s RadarLab HD (click to enlarge):

The red boxes indicate marine warnings. It’s not obvious in this shot, but as time moved on you saw that only the top half of the line was under a warning- I believe this is due to the fact that the National Weather Service only issues marine warnings out to a certain extent. I wonder who (if anyone) issues watches/warnings to sea vessels outside of US waters… hm. A cool shot, nonetheless. Enjoy.
