NASA scientists say satellite remote sensing can help determine when water will fall from the sky several weeks in advance. It can pinpoint how much water is available in snowpack and how much water is available in the ground. It’s crucial information during California’s drought.
Duane Waliser is a research scientist at NASA’s Jet Propulsion Laboratory. He’s using satellite remote sensing to predict a tropical weather pattern that produces heavy precipitation. It’s known as an “atmospheric river.”
“One of these rivers transports as much water at any given time as about five to ten Mississippi Rivers, so it’s very significant, and about 20-to-30 percent of that often ends up in the form of precipitation.”
Scientists can now forecast the weather pattern as much as four weeks in advance. The Department of Water Resources says the information will help the state better prepare and respond during droughts.
When it comes to rain and snow most of California is running below average this year, and little is forecast in the near future.
If you spent time on the water at Lake Tahoe last year and thought it looked a lot cloudier, you're right. UC Davis researchers say extreme weather — drought followed by heavy rains — caused clarity in 2017 to drop to its lowest recorded level.
(AP) — Despite dry conditions in much of the state, water managers say it's too early for fears that California is sliding back into drought as abruptly as the state fell out of it.
Caltrans is worried about the possibility of dead trees falling onto some California highways. The agency has already removed 107,000 trees. Now the agency is getting ready to remove another 54,000 trees, including some on private land.
Sacramento city council voted in favor of a proposal that makes some drought watering restrictions permanent.
