NWS: Tornado Surveys Could Take Days, Even Weeks

 

110428010337_005-Alabama-tornado-damage-courtesy-Montgomery-AdvertiserAfter one of the largest tornado outbreaks in recorded history, the National Weather Service is trying to determine how strong each tornado was.  Wednesday’s tornado outbreak killed more than 300 across six states, making it one of the deadliest tornado outbreaks in US history.  With so much destruction, the work that lies ahead for communities and meteorologists is daunting.

Normally, a storm survey will only need to take a look at a building or two, or at worst a town or two.  This storm survey will cover dozens of towns and many damage paths.  Normally, a storm survey will take just a day or two.  But in the hardest hit areas it’s expected to take much longer.  The National Weather Service in Birmingham is warning it could take weeks for them to finish their work and complete their reports on every storm track.

At this hour, the NWS In Birmingham has only reported three tornadoes with winds of 140mph or stronger.  They’re categorization on the Enhanced Fujita Scale is not final, but for now these three surveyed tornadoes are rated as EF-3 tornadoes “or higher.”  What this means is these tornadoes will likely be upgraded to a 4 or 5 before all is said and done.

In the one confirmed EF-5 tornado in Mississippi, 14 people were killed in and near the town of Smithville.  The tornado was on the ground for less than 3 miles but was half a mile wide and produced some of the strongest winds ever seen on Planet Earth.  At least three other tornadoes touched down in this area of northern Missisippi, early reports are that those tornadoes were rated between an EF-1 and EF-3.

We’ll continue to follow the latest developments from the south, but I’m hopeful that we’ll soon return to forecasting weather here in Iowa.  Because we all know big storms do not stop others from coming in the future.
