Serious rainfall situation for Texas + Louisiana Gulf Coast due to Tropical Storm #Nicholas. Forecast for Houston? 8-16 inches - heaviest tonight into Tuesday AM. Rare "high risk" of flooding middle-upper Texas coast. wapo.st/3hs6J4p
Here's a model simulation of #Nicholas making landfall tonight and its rainfall...extremely heavy rain esp east of where it comes ashore. @NWSHouston has said rates of up to 3-4" per hour.
As always, our friends @SpaceCityWX and @MattLanza providing excellent in-depth local perspective. They rate the flood threat at level 3 of 5 for Houston, with potential 100s of homes flooded.
Update: @NHC_Atlantic now has tropical storm warnings for the entire Texas coast (blue shaded area) and says #Nicholas could even reach the middle Texas coast as hurricane tonight.
The latest: wapo.st/3hs6J4p
NEW: Houston-Galveston area now in a "high risk" zone for excessive rainfall through Tuesday morning due to #Nicholas. Per @NWSHouston, high-risk days only make up about 4 percent of forecasts but are associated with 40 percent of all flood fatalities.

#Nicholas made landfall along the middle Texas coast overnight as hurricane, unleashing wind gusts up to 95 mph, a surge over 4 ft, and 14" of rain in Galveston. 500K lost power. Now a tropical storm, it's a serious rain threat for Louisiana. wapo.st/3zb20dx (1/x)
The problem? The storm is forecast to slow to crawl, unloading widespread 5-10" of rain in waterlogged southern Louisiana, just ravaged by #Ida. Rain could linger for 36 hours and isolated totals to 20" poss. (2/x)
A rare "high risk" of flooding/excessive rain in Beamont-Port Arthur to Lake Charles area, which was socked by two hurricanes last year while a moderate risk extends into New Orleans. (3/x)

JUST IN: #Nicholas strengthens to hurricane. Winds gusts have reached 80 mph along middle Texas coast, with over 25K w/o power. Biggest hazard still expected to be rain/flooding.
Updated storm briefing: wapo.st/3hs6J4p
Some good news for Houston is that over the course of today projections have shifted to more of a coastal rather than inland track and heaviest rainfall may focus to its south, closer to Galveston area. Even so, heavy rain, flooding still poss there into Tuesday.
Per @NHC_Atlantic -- #Nicholas produced sustained wind of 76 mph and gust to 95 mph at Matagorda Bay last hour. Over 30K without power along central Texas coast according to poweroutage.us

Storms coming tonight in the Mid-Atlantic and Northeast due to cold front. Yes, they will come one week after #Ida but they will *not* be as widespread or severe in most cases. wapo.st/3zX5i55 (1/x)
First around DC, most likely timing of showers and storms 5 to 10p although newer data leans toward 8-10p or even a bit later for a more widespread line of storms. Isolated severe possible...but heavier action probably to our north. (2/x)
Rain potential in Mid-Atlantic and Northeast generally 0.5-1", but pockets of 1-2" possible. In E Pa and parts of NJ/NY, they've had up to 600% of normal rain in recent weeks, so won't take much for flash flooding. (3/x)

Potentially serious weather day in DC area Wednesday-Wednesday night as Ida moves through.
1) Flooding risk, especially in our northwest areas
2) Severe storm/tornado risk in the immediate area
Detailed briefing: wapo.st/3mPNbuo (1/x)
We expect 1-3" of rain in the immediate DC area thru Wednesday night; with some localized flooding issues. But more significant flooding issues possible west and northwest toward I-81 where 3-6"+ possible. (2/x)
River flooding will become a concern by Thursday due to all of the rain not only falling from this event but we've had more than twice the normal rainfall this month. Major flooding forecast for Monocacy River in Frederick. (3/x) Graphic via @NWSMARFC

The latest on #HurricaneIda, very serious situation for Louisiana:
* It is strengthening, quickly, and projected to be a Cat 4 by Sunday
* Devastating impacts for coastal La: surge up to 10-15,' destructive winds
* But for #NOLA this is not Katrina.
wapo.st/3zrY1Kj (1/x)
New Orleans projected to see 8-12+" of rain, tropical-storm to maybe hurricane-force winds. Flooding, outages likely. But $14 billion flood protection system *should* protect it from Katrina-like surge. Also, Ida not as big as Katrina and peak surge will not come as close. (2/x)
Another development w/ #Ida: Landfall timing has shifted slightly earlier...reliable models showing landfall Sunday evening. Conditions will begin to deteriorate early Sunday morning in SE Louisiana. (3/x)
