The amount of products that a country makes,its manufacturing activity can give you an idea of how that country's economy is doing. In the U.S., manufacturing is up. There's a new report out that says the industry got bigger in August. That is the 13th month in a row that it's expanded. But some experts are warning that these numbers can be open to interpretation, and they're concerned that the manufacturing industry might run out of steam. The stock market had a positive reaction though to yesterday's report. The Dow Jones Industrial Average, a collection of some of the most traded stocks on Wall Street, jumped up more than 250 points.

Hurricane warnings and watches along parts of the North Carolina and Virginia coastlines. Some people are being told to get out of the area. All because of Hurricane Earl. It's getting closer to shore. And this weekend is Labor Day, one of the last big weeks for summer vacations. But a lot of people may be steering clear of the beach. Experts say Hurricane Earl probably won't actually reach shore, but it will affect the shore. The storm is about two hundred miles wide, and it could bring heavy rain, gusty winds and high surf along the coast. Some swimmers are already dealing with rip currents, strong currents that can pull you away from shore. A lot of experts say if you are ever caught up in one of these things, you should swim parallel to shore until you are out of the rip current and then start making your way back. Rob Marciano caught up with some rescue workers in Virginia Beach to talk about some of the dangers there.
