Day 271: Tropical Depression #16 (Nicole?)

Day 271 (a)

Yesterday (Monday) was a wild weather day. Los Angeles set their all time record high temperature of 113F; records date back to 1877! Wilmington, North Carolina set their all time record 24 hour precipitation total…(in excess of 10″, but I don’t know the exact value). Also, tropical depression #16 developed south of Cuba.

As indicated in the official forecast from the National Hurricane Center (NHC) above, tropical depression #16 is forecast to develop into Tropical Storm Nicole during the day tomorrow. Again, the official forecast is above. A series of model forecasts (of track) can be found below.

Day 271 (b)

In any event, tropical storm Nicole (if it develops) won’t last very long. It will be ingested into a broad baroclinic zone associated downstream of a long-wave trough over the eastern United States. In layman’s terms, it will transition from a true tropical cyclone to something more typical of the northern United States — an extratropical cyclone. In any event, deep tropical moisture, broad baroclinic zone, and prolonged resonance time all point toward a heavy rain event in areas that just saw a heavy rain event. Expect widespread flooding to continue.
