Yesterday's rainfall totals

* Drying out, more 90+ days on the way: Full Forecast *

Some impressive rainfall totals have come in from yesterday's deluge that caused flooding in many locations. Thought I'd highlight some amounts which varied substantially (highest amounts from northern Fairfax county through northwest D.C. and into central/southern Montgomery county):


National Airport: 0.52"
Dulles Airport: 1.39" (record for date)
BWI: 0.89"

Weatherbug (h/t Jennifer Gilmore, Senior Marketing Director, Weatherbug):

St. Francis / St. Camillus on New Hampshire Ave in Silver Spring, Md: 4.14"
Adelphi Elementary in Adelphi, Md.: 4.05"
University of Maryland main campus in College Park, Md.: 3.73"
Chevy Chase Elementary in Chevy Chase, Md.: 3.64"
Bradley Hills Elementary in Bethesda, Md.: 3.29"

CWG readers (via comments and Twitter):

@jojo2008: 2.75" in NE DC (Capitol hill area) thus far [through 2:37 p.m. yesterday]
@steske: I'm sure glad that second line fell apart/went south late yesterday because I had received 4.22" from the first line here in SS/TP [Silver Spring/Takoma Park]. Now have gotten 8.23" for the month.
@Joel_M_Lane: My rain gauge reading in North Arlington near Marymount was 3.1" at the end of the day. About 2.7 of that fell before 730 am or so
@joshlarson: parents in Chevy Chase are reporting over 4" of rain in the past 24 hours, for a monthly total of close to 9"

See also National Weather Service rainfall reports (published at 12:27 p.m. yesterday). For doppler radar estimated totals through yesterday mid-morning, see our post from yesterday.
