More rain gauges and an experimental weather sensor will be installed in the Green River basin to help boost the odds that federal officials can predict which storms might lead to flooding.
These systems, which are already used in California, measure water vapors in the air and wind speed and direction several miles above Earth's surface. Forecasters may be able to use this information to better predict whether impending storms will have enough rainfall to cause flooding within 24 hours in advance.
The new rain sensors are not foolproof, though, Colman said. They are still experimental, and one of the weather service's most difficult tasks, technologically, is gauging how much rain will fall during a given storm.
"But if before we were calling for 2-4 inches of rain and this lets us refine that to say 2-3 inches ... even removing that bit of uncertainty will be helpful," Colman said.
