Some parts of Utah received more rain on Friday than they do normally in six to 12 months, said David James, BYU weather station overseer.

Three to six inches were common in southern Utah, he said. Northern Utah and Utah County received a half-inch to an inch -- nearly a month's worth of rain.

"The downpour in Utah Valley caused roadways to flood," James said.

Another complicated storm system is expected to move through the area on Monday and Tuesday, but is not expected to be as wet as Friday's system, he said.

"Showers and thunderstorms are possible both days," he said. "Cool air will follow with highs dropping back into the 50s and 60s. Lows will be in the 30s."

Rainfall totals for the period of Oct. 3 through 7 included 3.10 inches on Timpanogos Divide, 2.15 in Payson, 2.04 at Deer Creek Dam, 1.89 in Cedar Hills, 1.85 in north Pleasant Grove, 1.79 in Highland, 1.60 in Santaquin, 1.58 in Eureka, 1.57 in north Orem, 1.5 in north Provo, 1.41 in Lindon, 1.39 in Springville and Provo-BYU, 1.37 at Spanish Fork, 1.31 in Alpine, 1.30 in Nephi, 1.27 in Woodland Hills, 1.17 near Thanksgiving Point, 0.92 at Lake Shore, 0.88 on the Lehi Bench, and 0.73 at the Provo Airport, James said.

"There is no doubt that fall is here in Utah," he said. "The leaves are changing colors in the valleys. Air conditioners have been turned off. Outside watering systems should be winterized."

Autumn rains have now soaked the valley and there is snow in the mountains. The Utah Division of Water Resources recommends to not do any outside watering until the next irrigation season in late spring, James said.

"There has been plenty of rainfall in September and October," he said. "The ground is saturated in many areas. It's also time for lawns to go dormant."
