Congratulations, AccuWeather!

The "eye" of the Snowicane over western Long Island

My colleagues in State College did an amazing job on the "Snowicane" that struck the Northeast last week. They realized, in advance, how intense and destructive the storm would be.  Normally, a "blizzard" does not knock out power in significant numbers.  This storm, with 90+ mph gusts, caused power to be lost to 1,000,000 electric "customers" (homes and businesses) which is approximately 3,500,000 people. The storm also dumped more than 30" of snow in many areas that the wind whipped into 5+ ft. drifts.

AccuWeather's forecasters realized all this as the storm developed. Given that huge numbers of people who would be without power in the cold surrounded by deeply drifted snow, they coined the term Snowicane to differentiate it from an ordinary blizzard. Since it would have a tight circulation similar to a hurricane (note the "eye" in the radar image above) and barometric pressure similar to a Category 2 Hurricane the term was apt.
The graph of barometric pressures was just like a hurricane's

So, it was with dismay that I read this story in today's Wichita Eagle (pg. 6A) filled with criticism from the National Weather Service. Especially amusing was the criticism that AccuWeather put out the forecast when the storm "hadn't yet fully formed."  Guys, that is what a warning is supposed to do -- let people know what is going to happen.

I continued to read my Sunday paper and turned to page 12A and read this story about the power outages in the Northeast which states,


CONCORD, N.H. —Frustration turned to resignation Saturday for hundreds of thousands of people in the Northeast struggling to survive another day waiting for utility crews to restore electricity after powerful storms socked the region with heavy snow, rain and hurricane-force winds.
The highest wind reported from the storm was 91 mph off the coast of Portsmouth, N.H. —well above hurricane force of 74 mph. Gusts also hit 60 mph or more from the mountains of West Virginia to New York's Long Island and Massachusetts.  [Note, there were even stronger winds as my friend Jesse Ferrell documents in his blog]


Hmm.  "Hurricane force winds + heavy snow + westward moving storm + eye and banded structure" = "Snowicane" anyone?  By getting the word out, AccuWeather gave people the vital tool of information which they could use to buy a generator, stock up on food and medicine, top off the gasoline tank, etc., to mitigate the effects of the storm. 

Anyone who has read this blog or who will read Warnings knows that I am a fan of the National Weather Service. They do vital work for the pubic and we in private-sector meteorology depend on their data infrastructure. But, the griping about AccuWeather's clever way to get people's attention in advance of an extremely dangerous storm should have earned kudos rather than criticism from our colleagues in the NWS.

    Hi Mike,

    My problem with AccuWeather using the terminology of snowicane is the same one I have with the NWS using Tornado Emergencies. It weakens the message of "ordinary" storms, which, I might add, still have the potential to destroy life and property. You yourself have come out against the use of Tornado Emergencies. How is this any different?

    Where do we stop? What will AccuWeather call the next event that is bigger than this one? If I'm a resident in the NE and I survived this event just fine, I guess I don't need to worry about ordinary nor'easters or blizzards because even "snowicanes" don't really affect me.

    Pat,

    I see the two issues as different. But, because this (at least to me) requires more words than I can write in a comment, I am going to do a separate posting. Thanks for the suggestion.

    Mike

Midnight: The East Coast Threat for Tornadoes and Severe  Thunderstorms Has Ended 3:50pm. Tornado watch for the Middle Atlantic Region. 2:30pm Tornadoes are also forecast in the South. 2:20pm. 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.

Updated Freezing Rain and Heavy Rain Forecast

Note: An Updated Forecast is Available HERE Freezing Rain The National Weather Service has now issued winter weather advisories, two warnings and a watch. 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 is 0.1 to .25 inc
