Het is ook niet het tornadoseizoen. Komt behoorlijk onverwacht.

Daar komen een paar beste blokken ijs naar beneden. Vraag me af of z'n zwembad schadevrij was.

Zo'n liner is duur. Maar inderdaad, er kan van alles kapot met zoveel geweld.

Jemig, ik was het al bijna vergeten.. Het nieuwe tornadoseizoen staat weer op het punt van beginnen

quote:

OKLAHOMA CITY -- Sunday will be mainly windy and mild with temperatures warming into the 60s and 70s. However, a slight risk of severe thunderstorms and a high risk of wildfires will develop by late afternoon.

Regarding the severe weather risk, isolated supercell thunderstorms may develop after 3 p.m. east of line from Cherokee to Hinton to Lawton. Any storm that develops will move rapidly eastward at 50 mph and could produce large hail, damaging winds, and tornadoes. The probability increases from 30 percent in central Oklahoma to 60 percent in far eastern parts of the state.

As for the risk of wildfires, a red flag warning is in effect for areas west of an Alva to Chickasha to Duncan line between the hours of 11 a.m. and 9 p.m. Westerly winds of 20 to 30 mph with gusts to 50 mph will combine with very low humidity to produce extreme fire conditions.

A confirmed tornado in Franklin County is blamed for the death of a 61 year old man who was trapped under debris. Melvin Hambrick's mobile home was destroyed when the tornado touched down on U-T Farm Road in Estill Springs. His daughter and grandson crawled out but he died at the scene. Officials say the twister uprooted trees and narrowly missed an elementary school. Early on officials were pretty certain a tornado had hit their community. The National Weather Service in Huntsville, Alabama says a preliminary investigation indicates that an EF-2 force tornado hit Franklin County.

More dangerous tornado season expected
The 2011 tornado season has started quickly, with more reports of damage from storms and twisters in the past two days than there were during all of the first two months of 2010 -- a trend likely to continue well into spring.

Severe weather season, as it's often referred to by meteorologists, typically peaks during May, when meteorological conditions that lead to the development of dangerous thunderstorms are most abundant. These conditions -- including a sharp north-south temperature gradient -- have emerged early this year and, based on the expected weather pattern, will likely intensify in the coming months.

Heavy thunderstorms Sunday and Monday affected a large region from the Plains eastward to the mid-Atlantic and the Carolinas, resulting in a fatality from a suspected tornado in Franklin County, Tenn., according to WKRN-TV. Over those two days, there were 389 preliminary damage reports (wind damage, hail and tornadoes), including 12 reports of tornadoes.

The same type of event occurred just last week, when there were 32 reports of tornadoes in the Tennessee Valley and Deep South on Thursday.

Through Monday, there have been about 800 preliminary reports of damage from severe weather in 2011, more than 2.5 times greater than the number through the first two months of 2010. January and February 2010 generated 307 reports, including just one February tornado.

Thunderstorms and tornadoes develop out of a strong temperature contrast from north to south across the country, along with an ample supply of moisture from the Gulf of Mexico. Storm systems emerging from the Rockies and heading east ignite the meteorological fuel.

This is precisely the type of weather pattern that is expected to continue at least through May, which is when tornado season typically peaks.

The federal government's Climate Prediction Center forecast for March through May calls for temperatures that are likely to be warmer than average in the southern part of the country and cooler than average in the northern part of the country. Thus, the contrast will be more intense than in a typical year.

In addition, the storm track is expected to remain more active than normal because of the ongoing La Nina. This is one of the typical results of a La Nina: more storms moving out of the Pacific Northwest and northern Rockies into the Plains and eventually the eastern part of the United States than during a non-La Nina year.

That's been the case recently, and these storms have pulled moisture north from the Gulf of Mexico into the sharp temperature gradient, resulting in lines of dangerous thunderstorms. Last year, the tornado season started slowly, in part because it was cooler than average in the Deep South during the latter part of winter through the first part of spring.
