Tornado Strikes Chicagoland

By -

Update, 4:30pm Tuesday: NWS has determined an EF-3 tornado and has set 
up a special web page, here.  


Update: 10:15am Monday:  The best coverage I've found this morning was on WGN TV and it is here. There were five injuries, one critical. Clearly the damage was at least EF-3 intensity. 

-- original posting --

Since the tornado occurred after 10:45pm we don't have a lot of information but below is a first guess as to the path of the tornado. It appears to have been from east of Aurora to near Burbank. 


As of this moment, 11:48pm, three injuries have been reported and "considerable" damage has been reported. 

Below is the Doppler wind velocity data at 11:12pm. That was the tornado. 


Worse, at the same time, the circled black area is debris lofted by the tornado. 

There is indirect evidence that this was an EF-3 intensity tornado.

Per NBC Chicago:

According to trained weather spotters, multiple reports of damage have come in from Woodridge, with debris reported scattered across Interstate 355 and power lines and structures suffering heavy damage in the suburb.

UPDATE 12:45am: There are reports of people being taken out on stretchers. There is "heavy" damage to homes reported in Woodridge.

NBC says the image below is their "first look" at the damage.


Unfortunately, I don't think we are going to know much more until daylight as numerous streets are blocked by downed trees and power lines. One reporter said that police on the scene said they were "too busy" to talk to him.

The brown area has a significant risk of tornadoes. Remember: if a tornado warning is issued, go to your basement and get under heavy furniture like a pool table. Of, if your basement is finished, get into the bathroom. Go ahead an put a couple of water bottles and, if appropriate, diapers in your shelter area. Wear shoes.  If you don't have a basement or safe room, go to the lowest floor and get into a bath or closet in the middle of your home. Children should be put in the bathtub.  I'll update later today.

It may be a bit too large but, when it comes to freezing rain and slick roads, caution is usually the better course of action.  Here's a color code: Deep purple is an ice storm warning; serious condition where power outages are possible. Pink is a winter storm warning for significant icing. Deep green is a winter storm watch. I don't know why this is still a watch. If I were on the forecast desk I would have a winter storm warning for icing.  Dark blue is a winter weather advisory, a lesser condition, for icing.  Here is a view of the entire watch/warning/advisory area. The small area of green in Illinois is for flooding and, in Nebraska, for snow.  Here is a forecast of freezing rain amounts; totals to 6am Tuesday.  Color codes: Yellow is 0.25 to 0.50 inches. Power outages may occur in this areas. Deep blue i...
