Weather Radios

"Before they go out camping to always check our forecasts from the national weather service," Lawrence said. He also said you should pack a NOAA weather radio if you want to stay informed on your trip."

Numerous news stories in the wake of the Arkansas flood tragedy last week have advised people to obtain and carry NOAA Weather Radios. Examples here, here, and here. 

Only one problem:  The weather radio channel that served the campground was out of service that night and a radio wouldn't have gone off.  Details here. 

This isn't the first time this has happened. In November, 2005, a tornado struck Evansville, IN at 1:50 am. Immediately, the "buy a weather radio" news stories began. But, in that case, like the Arkansas floods, the weather radios didn't go off.  Twenty-five people died. 
In both the Arkansas flash floods and the Evansville tornado, the local NWS issued timely, outstanding warnings that could have saved lives. But, the NWS technology to wake people up failed. This is why I continue to be a fan of sirens and a fan of the emerging technology of putting warnings into GPS-equipped cell phones. Modern technology for both sirens and cell phones will solve the "overwarning" problem associated with the weather radios (i.e., the radio waking you up even when you are outside of the threat area). 

It is fine with me if people want a weather radio. For the low cost, it is probably a good investment. But, it is dangerous to depend, solely, on weather radios -- especially in remote areas.  The system is not very robust. A mix of technologies is more fail safe.

UPDATE:  Commenter Bill makes an excellent point. NOAA weather radio operates on five frequencies. If you are traveling, you have to tune the radio to the appropriate frequency in order to get a warning. As I say above, it is not a robust system because there are too many points of failure. Thanks, Bill.

    People would also have to remember to program for the area they are traveling to. Most radios are programmable now and people program them for home. The radio won't work for the area you're traveling to unless it is an "open" NOAA radio, or you program the local codes.

A couple of tornadoes, hail and wind gusts to 65 mph are possible with these storms. This includes NYC and Philadelphia.  1:05pm. The tornado risk has been extended northward into New York. 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
