Saturday was Charleston’s rainiest Feb. 23 in record-keeping history, the National Weather Service reported.

Rainfall downtown totaled 2.09 inches by about 5:30 p.m., beating the previous record of 1.24 inches on Feb. 23, 1991.

North Charleston saw even more rain. The NWS station at the airport recorded 2.22 inches by 5:30 p.m., beating 1984’s record of 0.94 inches.

So far the month has been Charleston’s second rainiest on record.

As of Saturday afternoon, 8.23 inches of rain have fallen since Feb. 1, trailing only 1998’s all-time February high of 10.17 inches.

And even more is on the way. The National Weather Service has issued a hazardous weather outlook for much of the Lowcountry through Friday, with more heavy rain expected Monday.

Today should offer a brief respite from the damp, though. The day will be mostly cloudy and gradually sunny. The high temperature is expected to peak near 69 degrees.

Flooding early Saturday made many downtown streets impassable later in the afternoon.

City police reported several road closures, including Huger Street at King Street, Lockwood Avenue at Brittlebank Park and Line Street at the Crosstown Expressway.

Before noon there also were reports of flooding on Johns Island near Plowground Road and on Toogoodoo Road in Meggett.

The National Weather Service had issued a flood advisory at 10 a.m., which was allowed to expire at 1 p.m. The rain slowed down Saturday afternoon.
