How Much Rain in Central Maryland Over The Last 6 Days?

3 inches of Rainfall Sept.29-30

While South Carolina is suffering from extreme rainfall, here in central Maryland we received quite a bit as well over 5 days last week. Unfortunately for parts of South Carolina, some towns recorded up to 24" of rain. Here in the Washington, DC area we received over a fifth of that, and still, that's more than a month's worth of rainfall. 
   Rains deluged the Mid-Atlantic and southeastern U.S. when cold front stalled over the region and areas of low pressure developed and moved along the front. (Meanwhile another low is off the coast of the Carolina's and generating more rains there. Here in the Mid-Atlantic, high pressure moved into the region and the sun has finally returned.

2 1/2 inches of Rainfall Oct. 1-3

    So, from Tuesday Sept. 29 through Saturday  Oct. 3, the just east of Washington, DC, (like College Park and Bowie, Maryland) 5.5" of rain fell.  4. 3" of rain fell on Sept. 29-30 and 2 1/2" fell from Oct.1-3.
Here's a couple of photos from our rain gauges on Sept. 30 and then again on Oct. 4.

The meteorology behind South Carolina’s catastrophic, 1,000-year rainfall event 

The rains are tapering off in South Carolina after a disastrous weekend that brought over two feet of rain and catastrophic flooding. Dams have been breached, rivers are at record flood stage, homes and cars are filled with water and multiple people have been reported dead in the disaster.
