A powerful storm system that brought heavy snow, flooding, high winds, ice storms, and deadly tornadoes yesterday continues to sweep across the Eastern U.S today. Tornado warnings have already been issued for coastal North Carolina this morning, and tornado watches are up for much of eastern Virginia, North Carolina, and Maryland. However, the front that brought dozens of tornadoes to the Southeast yesterday has lost much of its punch, and only weak tornadoes are likely today.
Hardest hit yesterday was Enterprise, Alabama, where a strong tornado 200 yards wide hit the high school, killing at least eight teenagers, according to preliminary reports. According to the Tornado Project, this is one of the ten most deadly tornadoes to hit a U.S. school. The last tornado to kill so many school children occurred in 1967 when an F-4 tornado hit Belvidere High School in Illinois. The storm hit while high school students were boarding sixteen buses already containing elementary school students. Twelve of the buses were overturned or thrown. One bus driver and 12 students were killed after being "tossed like leaves" into adjacent fields. Students and teachers used school doors and plywood from nearby houses as stretchers for the injured students, of which there were 300. In nearby Harvard, a school bus was ripped in half and thrown into power lines as the driver and 20 students hid in a ditch.
The Enterprise tornado was an EF-3--Enhanced Fujita Scale 3--with winds of 136-165 mph. Radar imagery of the Enterprise storm (Figure 1) shows a classic hook echo characteristic of a strong or violent tornado. The Doppler radar winds (Figure 2) shows the classic signature of a strong tornado--blue colors right next to red colors, indicating winds moving towards and away from the radar in a tightly rotating storm. I've also saved a radar animation of the tornado as it passed over Enterprise.

A confirmed EF-3 tornado hit Howell County, Missouri, killing 7-year old girl and injuring four people at 6:33am Thursday. This tornado had a 15 mile long path up to 1/4 mile wide.
Preliminary reports indicate that at least 15 tornadoes hit Georgia last night, killing eight and injuring many more. Americus, Georgia, where two people died, was particularly hard hit. The twister struck a hospital, destroying its fleet of ambulances and forcing closure of the hospital. I've also saved a radar animation of this storm.
