12:35 p.m.: Light to occasionally moderate rain is still swirling around much of the area as temperatures range from near 40 to the mid-40s. Rain should generally wane as we head through the afternoon, though it remains likely at times for at least several more hours. Snow totals out west are approaching 30” in spots like Davis, WV. Otherwise, things appear to be on their way back to normal as area airports and Metro re-open this afternoon.
From 10:35 a.m.: Sandy is spinning itself out to our northwest this morning, with central pressures rising into the 980s (millibars), which is significantly weaker than it was at landfall. However, the impacts persist locally, and across much of the eastern United States.
Winds continue to dwindle, eventually sustained around 10 mph by late day, down from about 15-20 now. Higher gusts are likely as well, but nothing damaging is expected from here out. Rain will also taper, though it’s a cold rain and it’s going to last off and on into the afternoon, with some moderate activity in the area still right now. There could even be wet snowflakes mixed in, particularly north and west of the city, but potentially anywhere.
Rainfall totals across the area have largely ended up in the 4-8" range, with lesser totals to the southwest and higher ones near the bay and east. Through posting, Reagan National is up to 4.62”, Dulles is at 5.26” and BWI is at 6.46”. Additional ranfall today should not add significantly to these numbers.
Coastal and tidal concerns are not done with the weakening of Sandy. North winds that were pushing water out of the bay are now shifting to the south which is causing waters to rise. Jason Samenow reports on a coastal flood warning that is in effect through 8 a.m. Wednesday for water levels 2 to 4 feet above normal. There has been some minor flooding in Annapolis as well.
The flooding story is likely to get larger on area rivers. The National Weather Service is forecasting between moderate and major flooding along the Potomac, the Monacacy, and other tributaries in the region. Some good news here is that forecast levels have come down a bit since yesterday. Places like Little Falls were scheduled to reach major flooding and are now expected to just tip into moderate at around 12.2 ft.
Already this morning, waters are rising to near flood level in Georgetown as well as other places along the Potomac.
