Arizona Roads Flooded During Monsoon Rains

Posted by on Aug 24, 2016 in Blog

Beginning in late June, the mercury in Arizona rises to record levels. The dry grass bakes under the sun and drivers try to find shade when parking the vehicles. Then, there is an increase in the winds, bringing clouds and the development of cumulus thunderheads. The anticipation for the first raindrops is high, signaling the arrival of the monsoon reasons. While the moisture is welcome, it can also be the cause of roads flooded during monsoon storms.

The monsoon season typically is considered to begin in mid-June and end along with the month of September. Between mid-July and mid-August, the highest level of rains occur. However, approximately fifty percent of Arizona’s annual rainfall occurs during the monsoon period. The average annual rainfall in the state measures just 12.5 inches, although the measurements can vary significantly from one area of the state to another. More of the rain typically falls in the mountainous regions, such as the Mogollon Rim and the Sky Islands.

A monsoon storm is caused by warm air which creates low-pressure levels at the surface. In turn, the low pressure acts as a magnet for moist air from the oceans. In Arizona, the winds usually are from the west, but during the summer they shift somewhat to bring moisture from the Gulf of California and the Gulf of Mexico. The result is a pattern of heavy rainfall followed by reduced rainfall. The pre-rain period can be marked by massive dust storms

In North America, monsoons occur over parts of Utah and Colorado, New Mexico, Arizona, and Northwest Mexico. It is surprising to many people that monsoons occur in the United States since they are mostly associated with countries in Asia and Africa. The U. S. Versions are not as strong as those in the Asian storms, but the storm cycle is similar to other areas of the globe.

Monsoons are characterized by heavy rainfall during a short time period. In mountainous areas, the water torrents can increase rapidly. The force of the flash floods is able to topple trees and bushes, as well as to pick up and move sizable boulders. The results in areas which have been stripped of vegetation due to a fire can include massive mudslides which can wipe out trails and cover roads, causing a hazard to those not familiar with the tremendous force of the waters.

The volume of water and the speed with which it moves can create hazardous conditions for drivers. It can be difficult to accurately estimate the depth of water when approaching areas which are flooded. There can be potholes and underwater hazards such as live electrical wires.

The temptation to drive around barriers and warning signs can be tempting but can also lead to a disaster. Laws to back up the warning can cause cost money. It is best to abide by the warning signs and avoid driving during the periods of potential flash floods.
