0.88″ of rain at the airport Wednesday takes the yearly total over 33″, almost 13.5″ above average to this point in the year.
Updated 6/20 at 11:51 AM with a few more rain totals found on Twitter; 6/20 at 12:22 PM with link to cooperative rainfall observations relayed by the National Weather Service in Charleston.
The Flash Flood Warning has expired and streets in downtown Charleston are gradually reopening to traffic (including the Crosstown, which is now fully open again). Be mindful for side streets still inundated with water; if you come up on a flooded road, consider another route. It’s nearly impossible to judge floodwater depth at night.
Expect mid-80s tomorrow; more storms are possible in the afternoon. Don’t think they will be quite as widespread as today but with a moist airmass in place, we could still see some downpours.
Flash Flood Warning up for the Charleston metro area through at least 6:15 PM.
Significant flooding is underway in downtown Charleston. The Crosstown has been closed and numerous roads are currently underwater. DO NOT DRIVE IN DOWNTOWN CHARLESTON!
Additional heavy rain with a possible damaging wind threat is advancing into the metro area from the west. Need to watch this carefully.
