A team of Israeli scientists have devised a way to predict the intensity of flooding by turning cell towers into hygrometers, measuring humidity

Researchers from Tel Aviv University believe they've found a way to detect the severity of an oncoming flood in any given location using date from the area's network of cell towers. But it doesn't make use of human to human communications; instead, it revolves around measuring humidity in the air.

The radio/micro waves from cellphones and cell towers are directly affected by the amount of moisture in the air, so by analyzing trends in signal strength, an accurate reading of the atmosphere's humidity around the tower can be taken. By relaying this signal back to researchers when a flood-causing storm is likely, they can attempt to predict the magnitude of the event pinned to specific geographic areas. It has also allowed scientists to gain weather data on remote areas they had never been able to track before.

Since cell towers are so numerous and prevalent throughout the world, and wireless carriers already track this specific statistic, so using this technique (and technology) to detect floods would require little more than funneling the data to scientists.

Dear Editor:

Where were you on this one? In the following lede sentence, first paragraph of article, don't you mean "data" rather than "date".

"...using date from the area's network of cell towers"

Robert1234: It would be nice to see the cell towers find a way to bring humanity to the people of Nazi Israel and remove the ghetto of Gaza. In violation of some 60 U.N. resolutions, Israel is one of the world's premier criminal nations and the ONLY nation on earth claiming the right to be a true apartheid nation. The real shame is that Jews worldwide are unable to see what Israel has done to their religion. Judaism is now a political statement, not a religion, and it's as abhorrent as any if the several dictatorships of the world. Odd, isn't it, that Iraq, Iran and Libya had more individual freedom and religious rights that Israel? The fact that Israel is THE problem in the Middle East explains a lot. Without Israel, things the world over would be better. Oh, and don't come up with the "God's people" crap. According to the text, Israel won't come into existence until Christ returns, and that sure hasn't happened. What that means is that, according to Judaism, this Israel is a fake and thus evil. Apparently, it's true, looking at what Israel has become.
