The portion of the country with some level of drought increased only slightly in the last week, but areas at risk for major crop losses and widespread water shortages jumped significantly, according to a report from the National Drought Mitigation Center.
Areas of the contiguous United States under extreme or exceptional drought conditions increased by an area roughly the size of Texas - from 13.5% of the land to 20.5% - in the past seven days, according to the Drought Monitor report released Thursday.
"It's getting to the point where some of the (agricultural) damage is not reversible" in the extreme-drought areas, said Brian Fuchs, a climatologist at the center. "The damage is done, and even with rain, you're not going to reverse some of these problems, at least not this growing season."
The areas newly put into the extreme category are spread over many states, including parts of Iowa, Illinois, Missouri, Nebraska, Oklahoma, Kansas, Arkansas and South Dakota. (See last week's map, for comparison with the one above.)
Meanwhile, the portion of the Lower 48 states under moderate or worse drought conditions rose slightly in the last week – from 63.54% to 63.86% – putting the contiguous United States in the largest drought by area in the report's 12-year history. This is the fourth consecutive week the Lower 48 set a Drought Monitor record in this category.
A week of very hot and very dry conditions – coming after roughly two months of similar weather – pushed more areas into the extreme or exceptional categories, Fuchs said.
Areas in the "extreme" drought category – the third most severe of four classifications – could see major crop and pasture losses with widespread water shortages, according to the center.
The early-striking, intense storm system that hit the country last week has many people wondering if this year's spring could be a repeat of the violent season we saw last year.
U.S. tornado outbreaks happen nearly every year, but outbreaks of this magnitude and the outbreak at the end of April 2011 are rare.
“A March tornado outbreak of similar scope to (the recent one) occurs roughly once a decade," according to Russell Schneider, the director of NOAA’s Storm Prediction Center in Norman, Oklahoma.
Prior to April 2011, the U.S. last saw an outbreak of that magnitude in April 1974, when 148 tornadoes swept across 13 states, killing 330 people, and injuring 5,484. The outbreak on April 27 and 28, 2011, is the second deadliest outbreak in U.S.history, since records have been kept. It resulted in 320 deaths as 305 tornadoes swept across four states.
Currently, the death toll from Friday’s outbreak stands at 39, with the latest death being 15-month-old Angel Babcock who passed away Sunday afternoon from injuries sustained during the Henryville, Indiana, EF4 tornado.
As surveys of the hard-hit areas are completed, the confirmed count could continue to rise. So far, this recent outbreak saw 128 reports of tornadoes across 12 states, with 45 of those tornadoes being confirmed.
These current statistics make March 2, 2012, one of the deadliest March days since 1994. If the death toll rises, this could be the worst March outbreak, which will not be confirmed until the National Weather Service completes its local damage assessments.
Given the severity of this recent outbreak, does this actually mean that we can expect another harrowing spring for tornadoes?
