Nora to unleash tropical
Nora will make landfall in the southwestern United States this week, despite dropping much of its wind force after making landfall in Mexico this past weekend. The tropical rainfall is expected to bring heavy rain to the drought-stricken region, raising the risk of flash floods, according to metrologists.
The former hurricane is forecast to dump a lot of rain on Arizona, New Mexico, Utah, and Colorado between Tuesday and Thursday. The chance of locally severe rainfall in far southeastern California will be restricted to Tuesday and Tuesday night.
“This influx of moisture will result in tropical downpours and the risk of flash flooding,” stated a meteorologist. Mudslides are also a possibility, particularly in regions where there have been burn scars.
Ahead of the heavy rains, flash flood watches have been issued for Palm Springs, California, as well as Phoenix, Tucson, and Flagstaff, Arizona.
In the strongest downpours, rainfall rates could reach as high as 1-2 inches per hour, causing rapid overflow into arroyos (dry stream beds) and poor drainage areas.
Forecasters advise drivers to use great caution on the roads since some routes may be inundated and choked by fast-moving water. Drivers should never attempt to drive across floodwaters since the water is likely deeper than it appears and the roads beneath it may be damaged.
“Some of these showers and storms will pass into Las Vegas. While there may be a few showers from Tuesday night to Wednesday, it appears that the majority of the action will be to the metrologists. Precipitable water, or the amount of moisture accessible in the atmosphere, is one of the indicators meteorologists use to predict the likelihood of heavy rain and how unusual a rain event would be for a certain region. Given the amount of tropical moisture present, forecasters estimate precipitable water values for this storm to be particularly high.
