Rain, wind, flooding to ease; sunshine Tuesday

 NOAA

Intense low pressure to our south has been pumping torrents of rain, gusty winds and loads of trouble our way out of the east for the past 16 hours or so. Rain totals are running from well over an inch to nearly 4 inches across the region.

Some locations reported rain totals in excess of 6 inches and even 7 inches, according to this morning's data from CoCoRaHS

Saturated soils and gusty winds to more than 50 mph in some spots have toppled trees. That has brought down power lines. Roads are flooded as many streams rise out of their banks ... Here's a rundown of some of the damage reported to the NWS.

It all reads a bit like a tropical storm. Happily, the whole mess will move out to sea today, bringing us a couple of days of sunny weather before the next cold front brings more rain.

Here are some of the rain totals and top wind gusts for the storm so far:

BWI:  1.75 inches  40 mph

Reagan National:  2.76 inches  50 mph

Dulles International: 3.76 inches

Martinsburg, WV:  2.04 inches

The WeatherDeck, Cockeysville:  1.61 inches  18 mph (about as high as the wind here ever gets, thanks to the anemometer's sheltered location).

The heavy rains have pushed streams throughout central and western Maryland to record-high flow rates for the date. Here's the map. Out on the Eastern Shore, strong rains will likely end the moderate drought conditions that have persisted since last summer. We'll get an updated Drought Monitor map on Thursday morning.

The storm's stiff east winds have pushed tides a foot or two above normal for today on the western shore of the Chesapeake.

A coastal flood advisory will remain in effect  until 4 p.m. today. Inland flooding is also a continuing risk today. A flood watch is in effect until 2 p.m. in the Baltimore area as moderate to heavy rain remains a factor until it tapers off this afternoon. Flooding creeks and streams, and urban runoff, will inundate low-lying areas. 

Never try to drive through a flooded roadway. It doesn't take much water to sweep your car - and you - away. Turn around. Don't drown.

NOAA

It will be interesting to see the Inner Harbor today as the rain flush out all the trash in the storm drains. Or maybe rains earlier in the spring have already purged the system. Got water? Got a camera? Send us a report.
