March 6, 2020) … Hold on to your surf boards and get the wax out. The surfers could be in for some seriously sick waves tomorrow and a beach-eater. We also have a Coastal Flood Advisory.
Delmarva WX … Hunter Outten … “Its official! We now have a classified bomb cyclone off the Mid-Atlantic coastlines. For a extra tropical cyclone to be considered as a bomb, there needs to be a pressure fall of at least 28mb in a 24hr time period. In 12 hours alone, air pressure has dropped from 1004mb down to 973mb and it’s still dropping. In half the time we have dropped 31mb in pressure and 21mb of that occurred in the last 6 hours! Not to mention in the Gulf Stream producing 35-45ft swells! This is the strongest coastal low since January 2018 that delivered our last major snowstorm.”
