Wireless Emergency Alerts (WEA) are a new service from U.S. weather service and FEMA. Starting in June, they will send a text message with a strange tone to your mobile device if you are in range of a Tornado Warning, Tsunami Warning or other major event (in the U.S. only). Major events include "Presidential Alerts." You do not need to sign up. Washington Post Capital Weather Gang has a few more details.

The (U.S.) National Weather Service has released its report on a strong tornado that occured in Iowa the evening of May 25th. On the evening of May 25th, 2008 a tornado rated at EF5 (estimated wind speed was around 205 MPH!!) obliterated half of the town of Parkersburg, Iowa. Eight people have died, and 70 were injured. Here is a PDF containing incredible pictures of the damage (taken by employees of the NWS during their survey). [more inside]

The weather just got a lot more accessible. The National Weather Service's weather data is now freely available in XML format for SOAP clients; it had previously been only available through commercial providers or in a difficult-to-decipher format. Not knowing anything about web services, I'm not sure about the implications, but I imagine that anyone who knows their SOAP could build their own weather app really easily.

Hurricanes really suck. Luckily our friends at the National Oceanic and Atmospheric Association have posted a FAQ to answer our questions. No matter how moronic the questions are.

19 inches of snow at Central Park and counting. This is now a top 5 snow storm in NYC history. In 1996 the accumulation was 24 inches.

It's big, it's bad, and it's coming your way. Beware Bonnie! No, no, wait. Hide from Hanna! Hmm, nope. Run from Rene! Geez, this naming thing isn't easy. How do you name a tropical storm? Should the name be masculine or feminine? Should it roll off the tongue with ease or be a mouthful? Are there some names you can't use? If a tropical storm was closing in on your neighborhood, what would you call it?

It really is amazing what kinds of cool, free, raw data you can get from the web (that other folks would charge you good money for), here are a few I've come across.

Weather, from the good folks at the NOAA/NWS
Geographic locations of zipcodes amongst other things from those pesky buggers at the US Census Office
Want reverse phone lookup data ? NANPA has the skinny.

So what other cool data feeds have people found out there ?
