East Coast Flood Threat Increases With Development Of Joaquin, Snowing Again In Fairbanks

Written by Mark Vogan on September 29, 2015 in Autumn 2015, United States of America with 0 Comments

Since the last US post yesterday, we now have Tropical Storm Joaquin spinning east of the Bahamas. This looks to support a secondary tropical invasion into the East Coast following the first soaking through the next 24-36 hrs. The first system lifts up through the Mid-Atlantic and Northeast but another southeastbound cold front looks set to lift out over the Atlantic and essentially pull the rich tropical moisture from TS Joaquin into the Mid-Atlantic and Northeast by this weekend.

SST’s and anomalies are plenty warm for further strengthening and or enhancing rainfall further.

Note the cold trough and storm over southern Alaska and another trough sitting along the Gulf Coast. A system will run up the coast bringing flooding rain as it connects with a cold front dropping out of the Great Lakes.
