Two days before the waters of the Guadalupe River swelled into a deadly and devastating Fourth of July flood in Kerr County, Texas, engineers with a California-based company called Rainmaker took off in an airplane about 100 miles away and dispersed 70 grams of silver iodide into a cloud.

At a news conference Monday, state officials said 101 people remain missing, including 97 in the Kerrville area.

A prominent senator is calling on President Donald Trump to reverse course on his proposal to slash the budget for the National Oceanic and Atmospheric Administration, making a case for America to be a world leader in the weather forecasting space instead.
