UPDATE OCTOBER 2, 2015. 4 AM CDT (9 UTC). Joaquin – now a Category 4 hurricane – has been slowly pounding the Bahamas and is only now slowly moving away from there. Meanwhile, local National Weather Service offices now believe that flooding caused by Hurricane Joaquin this weekend could be “historical” in parts of the U.S. Southeast and Mid-Atlantic. Flash flood watches have already been issued for parts of Northeast Georgia, South Carolina, North Carolina, and northwards into the Mid-Atlantic including Washington D.C. through Sunday night. Meanwhile, the hurricane will also likely impact broad swaths of the U.S. Northeast, including New York City and New Jersey. Heavy rain and flooding should start Friday and last through the weekend, possibly into early next week.
