Update on Tomas

Another report from Jeff Piotrowski at 9:30pm Central:

Looking NNW from Port-au-Prince see very heavy lightning all most nonstop very heavy storms near the city of Boucassin- Aubrey area. No local radar but I would expect 1-3 hr rain fall rates. I see over shooting tops with anvil crawlers NNW of my location. I would EXPECT major flooding to my north tonight. Death toll up to six west of Port-au-Prince west about 60KM. I also understand from a local Gov man told me that a small town on south shore East of Jacmel Haiti may have other victims at that location.

Jim & I were able to be part of the UN & US Army delegation today to inspect the tent city location in Port-au-Prince with UN police escort amazing experience.MAY GOD”S GRACE BLESS THESE PEOPLE!! 

Anvil crawlers are a form of horizontal lightning under the "anvil" of a cumulonimbus cloud. This photo is from Roger Edwards of NSSL:

In the tropics, this type of lightning is often associated with high rates of rainfall.

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
