Rain, courtesy the remnants of Tropical Storm Ida, has paused for some areas north and west of D.C., but is likely to start back up again for most everyone in the metro area later today and tonight. As of 1 p.m., rain had been reported at Reagan National Airport every hour since 2 a.m. yesterday morning.

Rain totals since the storm began late Tuesday night through 1 p.m. today are substantial at Reagan National (1.40"), Dulles (1.33"), BWI (1.16") and Andrews Air Force Base (1.61"). Southern Maryland has seen a bit more, with 2 to 3 inches reported.

Totals are downright impressive in Southeast Viginia, already nearing 7 inches in some locations Through 12 p.m. today: Newport News (6.76"), Hampton (6.40"), Norfolk (4.73"), Richmond (3.01"). Meanwhile, wind gusts across the same area have reached near and over 60 mph.

A state of emergency remains in effect in Virginia, where flooding is a threat through Friday. See below for flood video from Newport News.

As an example of the winds raking the coast to the southeast, latest observation at Norfolk, Virginia has northeast winds sustained at 30mph, gusting to 52.

Tom Skilling just reported a wind gust from Ocean City, MD over 100 mph on WGN!

Has anyone confirmed this?

"2 a.m. yesterday morning."

As opposed to 2 a.m. yesterday afternoon?

;)

Bombo47jea: I have not seen that report, and would be surprised of such high winds during this event. That said, Tom Skilling is a reliable source. Will look into it further.

To clarify: those wind reports were maximum gusts, not sustained winds.

The hidden trouble maker in all of these storms is the coastal flooding and erosions. I think I even heard somewhere yesterday where today (or yesterday) was the astronomical high tide ?which is the highest tide in like 4 month periods?. Anyone smarter care to share? I searched online for a good source, but couldn't find it.

However, I know that family was down on the bay yesterday pulling boats and pots out of the creeks on the middle peninsula as the tide was already running a few feet above normal.

Jamie:

I think you're talking about Proxigean tides, when a new or full moon occurs at the closest possible proximity to earth? The best discussion I found of that is here: http://www.astronomycafe.net/qadir/q1423.html This source does not list November 2009 as a time of extraordinary astronomical tides, but includes a link to another page on which you can calculate apogee and perigee points for any given year. The Old Farmer's Almanac also has some discussion of the phenomenon as well as brief mention of historical related weather events: http://www.almanac.com/content/proxigean-tides

Proxigean or not, a check of the NOAA Tide Prediction tables at the Chesapeake Bay Bridge Tunnel shows that Mean High Tides for November 11, 12, 13, & 14 of 2009 are 3 feet and over, which is on the high side but certainly not higher than that seen every month at that station: http://tidesandcurrents.noaa.gov/get_predictions.shtml?year=2009&stn=8863+Chesapeake%20Bay%20Bridge%20Tunnel (scroll down to see November).

I'd pull the boats off of a creek too, and yank the pots up besides. I re-wrapped all my lines last weekend and made sure the chafe guards were still good.

And while we're at it, here is the link to NOAA's Nor'Easter Mid-Atlantic QuickLook page, which shows the spread between the predicted and observed water levels at numerous points all up and down the coast, along with other cool data such as wind speeds and temps: http://tidesandcurrents.noaa.gov/quicklook/data/MID-ATLANTIC.html#8635750wl I believe this updates every 30 minutes.
