Oil, Ash and Deadly Tornadoes
Posted by Dan Satterfield
It’s been a busy month for those of us who forecast weather. Tracking volcanic ash using upper level wind forecast and using ocean current models to track the growing oil slick in the Gulf. Today it was a little of all three.
Oklahoma was hit by a swarm of tornadoes today. At least 4 are dead. Many people have lost there homes. Cars and large trucks were flipped in the air along I-35 and I-40. With modern technology, I could watch the same radar images that forecasters in Oklahoma were looking at. Large tornadoes show up very well on Doppler radar. Today they were very easy to spot.
In the Hollywood movie “TWISTER” the town of Wakita, Oklahoma is hit by a big tornado. Today, Wakita really WAS hit by a large tornado. See the radar image below.
As for the oil in the Gulf…
The slick is noticeably bigger on the NASA Terra satellite images today.
Ocean current models continue to indicate the oil will spread toward Louisiana. There is already oil spreading westward of the Mouth of the Mississippi and Northward onto Dauphin Island in Alabama.
The oil is showing up as gray and a dark color surrounding it in the middle right of the image to the left.
You can click the image and see a much larger version.
Now for the Volcano in Iceland…
It’s still erupting and the only reason air traffic is not snarled, is the upper level winds are blowing it south into the mid Atlantic. If the winds change and start blowing the ash toward Europe again…
Here is a pic from the NASA Terra satellite today.
There are several towns in Iceland that have been covered in thick ash from the volcano. That is not getting nearly the coverage that the flight delays are. You have to feel for those folks…
The nearby Katla volcano usually erupts within a few months of it’s neighbor. It’s eruptions are much bigger. MUCH BIGGER.
No sign of that happening…yet…
