Hurricane Season Ends, European Chill, Cool Video, Quake Off Jersey

Well, I hope everyone enjoyed their Thanksgiving and holiday weekend, did their shopping, etc. Back in California after a fun leg of flights today over the large storm system swirling in the middle of the country. More on that shortly. First, let’s catch up on some of the more interesting stories from the last week or so…

2010 Atlantic Hurricane Season Ends

First and foremost, today is November 30th, which is the last day of the Atlantic Hurricane season. That isn’t to say more storms can’t form, but in terms of statistics, this season is done. How did we do?

19 Named Storms
12 Hurricanes
5 Major (Cat 3+) Hurricanes

Normal is 11, 6 and 2 respectively. Here’s the official NOAA press release on the season. The season ends up tied for the 3rd most active on record (1887, 1995), and it ties for the second most hurricanes on record (1969). The money quote from the release (in my opinion):

“Large-scale climate features strongly influenced this year’s hurricane activity, as they often do. This year, record warm Atlantic waters, combined with the favorable winds coming off Africa and weak wind shear aided by La Niña energized developing storms. The 2010 season continues the string of active hurricane seasons that began in 1995.

But short-term weather patterns dictate where storms actually travel and in many cases this season, that was away from the United States. The jet stream’s position contributed to warm and dry conditions in the eastern U.S. and acted as a barrier that kept many storms over open water. Also, because many storms formed in the extreme eastern Atlantic, they re-curved back out to sea without threatening land.”

KTRK-TV in Houston compares some of the seasonal forecasts.

Some more perspective on the season and hurricanes in general, including a neat satellite derived rainfall map from this season.

Overall,  I think this season is going to go down in the books as a bust in general, namely because the U.S. was spared a hurricane hit for the fifth straight year, despite the hyperactive nature of the season. But the forecasts were very well done for the most part this season, and frankly, I don’t know that you can ask for much more than that, given our limited ability to predict weather and climate.

So what about next year? It’s obviously way down the line and there’s little skill in trying to make a forecast this far out. But, if you look at a couple of key El Nino area forecast, the ECMWF and the IRI, both indicate (an implied and/or average) weak La Nina persisting into next summer. Should that hold together, that would be one factor that would would favor another busier than normal season. Whether it’s even remotely as busy as this year…or busy at all…remains to be seen though. But that just gives you an idea.

Lastly with the tropics, some new online maps are available, indicating flood vulnerability along the coast due to storm surge. If you click the link in the article and tool around with the maps, some of them are interesting. Bottom line, there are a LOT of vulnerable places on this country’s coast to storm surge flooding.

Mildly similarly related…

There was an interesting article published in Friday’s New York Times about how Norfolk, VA is handling frequent bouts of tidal flooding.

Some cool video came out of last week’s big Western storm. This video was courtesy of Dale Ireland in Silverdale, WA (originally published in Cliff Mass’ Washington weather blog). Then of course, there was this priceless video from Seattle last week:

Here’s a radar loop from the snow in Seattle last week as well:

That Seattle snow made it to Salt Lake City last Tuesday, and here’s some really cool time lapse video of the snow rolling in, and a slower video that shows basically a wall of angry weather arriving:

Interesting AccuWeather blog post today about how the West is seeing absolutely phenomenal early season ski conditions…some of the best in years. It has been stormy…and it’s also been cold, helping a lot of ski resorts add more white gold to their slopes. Absolutely great conditions out West this year. Here’s an article on how citrus growers in Central California have been protecting their crops.

Cold in Europe

This winter is behaving (in some regards) oddly similarly to last winter. If you remember last winter, the US and Europe had it especially rough. Well, Europe is off to the races this winter too.

A few inches of snow for London…and a lot of travel disruptions.

The snow is disrupting school and life in the UK.

This follows some of the coldest November temperatures on record in the UK over the weekend!

Sweden is also seeing some of their coldest November weather in years.

The Eastern US will taste some cold weather, sort of driven by similar factors (and relatively, not nearly as cold) as we go through the next ten days or so. The pattern will also be ripe for the potential for at least some snow. More on that in coming days.

A few final things today.

USGS "Did You Feel It?" Map from today's 3.9 magnitude earthquake off Long Island.

From the head scratch department, dust storms can occur in the Arctic…and there’s an interesting driver behind them.

A 3.9 magnitude earthquake occurred around 10:45 AM today, about 120 miles ESE of New York City. The details on the quake are here. A ton of “Did You Feel It?” reports were received by the USGS from Long Island, New England, and New Jersey. Anyone notice this today?

And finally, in what is the most painful story of the day, another tornado hit Yazoo City, MS this morning. If you recall, Yazoo City was hit by a devastating EF-4 tornado back in April that killed 10 and injured dozens. From what I’ve read thus far, there were six injuries from this morning’s storm. More details if I get them.

More on some of the upcoming weather in the next couple days as I get myself caught back up on things after the extended weekend.
