Lo impresionante es lo de Alaska y lo de Nome sobretodo

Alaska está literalmente congelada Lleva todo el invierno tragandose fuertes borrascas, tiene que ser un infierno.
Para muestra una imagen del Modis del pasado día 23 de Enero.

Buenas, en Alaska estamos recolectando una bonita colección de records históricos de temperaturas negativas.
En Jim  River el día 28 se llegó a -80º F (-62,2º C) record de toda la serie histórica, hasta que petó la batería y dejó de enviar datos. Y en otras poblaciones las mínimas continúan sin dar tregua.
Os dejo varias datos de estaciones y la tabla de Jim River

El impresionante efecto Lake Efecct que se está produciendo en estos momentos sobre le norte de los estados de Illinois , Indiana y en menor medida en Winsconsin (Sur) y suroeste de Michigan.

Una Nortada de las del Cantábrico pero a los bestia.



As an arctic front plunges south across the area, a quick one to three inches of snow is expected this afternoon over the Chicago area. A lake effect snow storm will then set up over northwest Indiana tonight. Heavy lake effect snow squalls are likely to dump 6 to 12 inches of snow over portions of Lake and Porter counties.

Graphical Nowcast
NWS Chicago, IL



At 445PM CST...the main synoptic snow was slowly coming to an end as lake effect banding begins to ramp up. The main lake effect band is becoming better organized this hour and will bring heavy snow to many lakeshore locations...including the city of Chicago for the next few hours. Visibilities will quickly fall to one quarter mile or less in the heavy snows...and conditions can change wildly over a very short distance. The lake banding will eventually slide south and east overnight...significantly impacting Lake and Porter Counties in Indiana.

También ha sido bastante rancio el invierno por USA no???

Supongo que habrá una relación global entre el invierno frío en casi toda Europa, seco en la fachada atlántica y bastante templado en USA. Estamos tan acostumbrados a ver grandes temporales de nieve por ahí que se me antoja particularmente raro que no haya ocurrido.

Ya habíamos hablado de ello en Tropical... NorEaster al canto, y con nombre:

now Winter Storm Athena for the Eastern U.S.

ATHENA batiendo records:

“I am waiting for the locusts and pestilence next,” said New Jersey Governor Chris Christie at a press conference on Wednesday, after Winter Storm Athena punished New Jersey with heavy snows, high winds, and a 3-foot storm surge. The storm brought unexpectedly high snowfall amounts along a swath from Central New Jersey northeastwards across Southeast New York, Long Island, Connecticut, and South Central Massachusetts. The 4.7" of snow that fell at New York City's Central Park was the city's earliest 4-inch snowfall on record. The old record for earliest 4-inch snow was Nov. 23 in 1989. Last year's Snowtober storm brought the earliest 2" snowfall on record in NYC on October 29, 2011, but the city didn't surpass the 4.7" mark until January 21, as winter basically failed to show up. The 5.7" of snow that fell in Newark, NJ Wednesday was the heaviest single-day November snowfall on record in Newark (going back to 1931), and the earliest snowfall of that magnitude on record (the previous record was set just last year, when the Snowtober storm dumped 5.2" of snow on October 29, 2011.) Several locations in New Jersey and Connecticut recorded a foot a more of snow during Athena, with the storm's highest total of 13.5" recorded in Clintonville, CT. High winds combined with the heavy snows and rains to knock out power to 375,000 additional customers in New York, New Jersey, and Connecticut yesterday, and a storm surge of 2 - 3.5' hit most of the mid-Atlantic and New England coasts, from Virginia to Massachusetts. The storm brought waves of 20' to the waters offshore of Long Island, NY and near Block Island, RI. The top winds over water were 61 mph, gusting to 76 mph, in Buzzard's Bay, MA. Here are the top wind gusts from Athena as of 8 am EST on Thursday, November 8, 2012:

Y BRUTUS en camino sobre Nontana:

Here comes Brutus: major blizzard coming for Montana
Right on the heels of Winter Storm Athena comes Winter Storm Brutus--a powerful low pressure system that is taking shape over Southern Montana this morning. Light snows have begun in Southwest Montana, and will spread to the northwest across much of Montana and into western North Dakota this afternoon through Saturday. As much as 12” to 18” of snowfall is expected for several major cities in Montana, including Great Falls, and over 2 feet is expected in the mountains.  According to the Glasgow, MT NWS Facebook page, the current storm total snowfall amounts north of the Missouri River/Fort Peck areas would be within the top 10 two day snowfall totals across this region, going back 115 years. Strong winds will combine with heavy snowfall to produce blizzard conditions across northeast Montana. Brutus is forming in response to an usually large loop in the jet stream over the Western U.S. On the east side of the jet stream axis, a southwesterly flow of air has pumped in record-breaking warm air from the Desert Southwest. Sheridan, Wyoming hit 79°F Wednesday, breaking their previous all-time monthly record of 78° set on Nov. 5, 1975. Records go back to 1893. However, Sheridan will be on the west side of jet stream by Saturday, as the cold front associated with Brutus passes through Wyoming. This will bring Sheridan powerful northwest winds, 4 - 8 inches of snow, and high temperatures 50° colder than Wednesday's.

Hoy en las noticias: record de tornados en Estados Unidos para un dia de Navidad. Estos "yanquis" tienen de todo y en todas las fechas del año.
