NOAA's Hydrometeorological Prediction Center (HPC) is sounding the alarm bells about possible flooding in the mid-Atlantic, including the entire D.C. metro region.

In its "Excessive Rainfall Discussion" released at 2:41 p.m., it warned of a:

...VERY DANGEROUS EXCESSIVE RAINFALL/FLASH FLOOD EVENT FOR THE MID-ATLANTIC INTO NORTHEASTERN U.S...

and cautioned:

...SETUP IS SOMEWHAT SIMILAR TO THE JUNE 26-29...2006 HEAVY RAINFALL EVENT...

During that event, parts of the metro region received up to 10" of rain. (For more on that historic event, scroll through the archived coverage on CapitalWeather.com, Capital Weather Gang's predecessor)

HPC's technical discussion concludes:

RAINFALL RATES AROUND TWO INCHES PER HR ARE EXPECTED WITH LOCAL TOTALS OF 5-10 INCHES BY THU EVE.

We are currently analyzing the latest information and deciding whether to increase our forecast rain totals of 1-4" (with locally higher amounts).
