National Weather Service breaks down what valley residents can expect this monsoon season


When the first big storm of monsoon season hit earlier this week it brought lots of rain and a blanket of humidity with it.

According to the National Weather Service, Monday’s storm was the biggest so far.

“It had a lot of lighting,” said Ashley Wolf, meteorologist, National Weather Service.  “It was a bright show, but what was really impressive was the amount of rain that came out of it. We had 66 hundredths of an inch of rain.”

That’s more than July’s typical monthly average of rain.

“And we had winds that were severe in access of 60 mph, at McCarran airport; gusts of up to 68 miles per hour, which is really impressive for storms in the valley,” said Wolf.

The wet conditions bring lower temps but also humidity. 

“The dew point is a good way to determine how much moisture is in the atmosphere,” said Wolf.  “We went from 20-25 degrees to up to 60 to 70 degrees.”                                

Chances of thunderstorms, high winds and hail are something Clark County residents need to be ready for, despite this year’s monsoon season starting about a week late.

“It can go all the way to September and sometimes October,” said Wolf.  “For the next week or two, it does look like it’s going to be very active so people need to be prepared for any kind of thunderstorms that might roll through.”

The National Weather Service says flash flooding is the biggest concern with monsoon season and as they do every year, they’re reminding everyone to be cautious when driving near fast-moving water.
