Скачать или смотреть April 27 2011 Alabama Tornadoes - Radar and Tornado Tracking

Using images from http://mesonet.agron.iastate.edu/ and data from NWS survey pages, I have compiled a radar loop from the April 27 2011 Alabama tornado outbreak and labelled the image wherever/whenever a tornado was down. Note that the times and locations are not meant to be precise, just a general idea of where and when the tornado occurred. The primary purpose is to show which cell produced which tornado and which tornadoes were down at the same time.

PLEASE NOTE! The Marshall county MCS that dropped nearly a dozen tornadoes in the morning round is only labelled as a complex, since the series of tornadoes was too complicated to track precisely. I will probably go back later and fill them in anyway. I have also excluded a tornado from the noon round in Marshall county because HUN has not yet defined its precise time of occurrence. ALSO, only a few select tornadoes from MS and GA are labelled! Therefore, do not use this video to track tornadoes in any other state until I update this, as I will probably go back and fill the rest in later.

The survey data I used is from the event pages on the Huntsville, Birmingham, Jackson, Memphis, and Peachtree City NWS offices' websites. Also, data is considered preliminary and is subject to change.
