Using NASA's advanced Earth-observing satellites, scientists have discovered a new opportunity to build early detection systems that might protect thousands from floods and landslides.

Scientists at NASA are finding that with hurricanes, they can look at the cloud tops for clues about the behavior of winds below the hurricane on the Earth's surface.

NASA oceanographers agree that the recent La Nina in the eastern Pacific Ocean is not expected to have an effect on the Atlantic hurricane season this year. That's good news, because normally a La Nina tends to increase Atlantic hurricane activity and decrease Pacific Ocean hurricanes.

For many people, a monsoon brings to mind images of intense rainfall and high winds in faraway places. Actually, monsoons occur all over the globe, including North America. These seasonal reversals of winds trigger dramatic changes in rainfall and other weather events within a short period of time.
