Tropical Storm Christobal

By -
Tropical Storm Christobal continues to slowly strengthen in the Gulf on its way to landfall in Louisiana. Conditions will deteriorate on the northern Gulf Coast tonight.
Note that the winds are asymmetric; the there is much more wind above 40 mph (orange tinting) to the east of the center than to the west. That is going to cause a major problem with storm surge.

This map, click to enlarge, shows the peak storm surge potential. Evacuations are occurring in some coastal areas.

In addition, heavy rains and gusty winds are forecast to occur well inland.
I will be providing future information on Twitter @usweatherexpert.

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.

Note: An Updated Forecast is Available HERE Freezing Rain The National Weather Service has now issued winter weather advisories, two warnings and a watch. 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 is 0.1 to .25 inc
