Weather sites inundate users with an array of data and satellite imagery that pinpoint storms, highlight jetstreams, provide daily temperatures and forecast weather conditions for just about anywhere in the world. Others rely little on graphics, instead providing detailed information without the Internet's bells and whistles. A few sites even provide flight information to ease travelers' airport worries. The sites have the potential of saving lives by warning of hazardous road conditions and helping people find the best escape routes in severe weather. International and U.S. satellite maps detail current weather conditions.
Some images show time-lapsed cloud movements.
Others highlight current dew points, among other conditions. The Weather Channel's Travel Conditions , a link off the home page, lets users check flight information at 100 of the busiest U.S. airports. Vacationers will enjoy The Weather Channel's Boat and Beach site. It features a map of the United States that shows, by area, the intensity of the sun's rays or risk of sunburn. This is measured by an Ultraviolet Index.
