HURRICANE Nicolas Update 10pm Monday

By -
Nicolas attained hurricane strength as of 10pm.
No other updates.

4pm Nicolas' path forecast from the National Hurricane Center. The storm has sustained winds of 65 mph with near hurricane force winds forecast to exist by landfall. Pink = hurricane watch. A few power failures may occur/

Here is my characterization of the NWS's flash flood forecast for tonight. It is important to know that extreme risk (my characterization of the Hurricane Ida flood forecasts for the Northeast) is a rare forecast but disproportionately accounts for 40% of the deaths.  

Even though it is the NWS's forecast, I used Pivotal Weather's 
plot because of its depiction of counties and highways.
Most flood deaths occur in connection to driving.

Below is the same map with cities affected (via The Weather Channel):

Heavy rain is now moving into the greater Houston-Galveston area (blue arrow).


Below is the forecast of rainfall with this storm. 
Upper right is the Texas-Louisiana border. 

Update: From James Wilson.

A couple of tornadoes, hail and wind gusts to 65 mph are possible with these storms. This includes NYC and Philadelphia.  1:05pm. The tornado risk has been extended northward into New York. The brown area has a significant risk of tornadoes. Remember: if a tornado warning is issued, go to your basement and get under heavy furniture like a pool table. Of, if your basement is finished, get into the bathroom. Go ahead an put a couple of water bottles and, if appropriate, diapers in your shelter area. Wear shoes.  If you don't have a basement or safe room, go to the lowest floor and get into a bath or closet in the middle of your home. Children should be put in the bathtub.  I'll update later today.

It may be a bit too large but, when it comes to freezing rain and slick roads, caution is usually the better course of action.  Here's a color code: Deep purple is an ice storm warning; serious condition where power outages are possible. Pink is a winter storm warning for significant icing. Deep green is a winter storm watch. I don't know why this is still a watch. If I were on the forecast desk I would have a winter storm warning for icing.  Dark blue is a winter weather advisory, a lesser condition, for icing.  Here is a view of the entire watch/warning/advisory area. The small area of green in Illinois is for flooding and, in Nebraska, for snow.  Here is a forecast of freezing rain amounts; totals to 6am Tuesday.  Color codes: Yellow is 0.25 to 0.50 inches. Power outages may occur in this areas. Deep blue i...
