Odile Pushes North, Flooding Threat Increases
Tropical Depression Odile is spinning over northwestern Mexico and it’s now beginning to make it’s way into the Desert Southwest. While winds aren’t going to be a big worry, flooding rains certainly will be cause for concern.
Tropical moisture has been streaming in for nearly 24 hours and that’s already lead to rain moving though southern parts of Arizona and New Mexico. According to the Community Collaborative Rain, Hail and Snow Network (CoCoRaHS) more than 1.5 inches or rain fell near the towns of San Simon and Hereford in Arizona. And unfortunately, much more rain is expected in parts of Arizona and New Mexico.
A WeatherNation proprietary forecast model is suggesting upward of 5 to 7 inches of rain is possible when all is said and done. Other models have as much as 8 inches of rain calling by week’s end, but they’re likely overdoing it a bit.
The influx of tropical moisture and resulting rain has prompted National Weather Service offices in Arizona and New Mexico to issue flash flood watches for large portions of those states. Most of them are active through Thursday evening.
If you live in locations like Tucson, Phoenix or Albuquerque, stay weather aware through the end of the week. Sudden, heavy downpours could lead to fast-onset flash flooding. If you see water over a roadway, it’s never advisable to try to cross. One foot of fast-moving water is enough to float a car downstream.
All of this new rainfall is adding to an already impressive monsoon season in the Desert Southwest.
Just last week, Phoenix shattered a record for their wettest day ever — receiving more than 3.3 inches of rain in a 24-hour period. This is also one of the wettest Desert Southwest monsoon seasons in decades.
There have already been some pretty impressive instances of rain in New Mexico as well. According to the National Weather Service in Albuquerque, two-day rainfall totals have topped 3 inches near San Antonio. A couple of other location in New Mexico saw heavy rains as well: Mogollon saw 2.8 in inches of rain, while Bosque del Apache recorded 2.44 inches.
Much more rain is expected in the coming days and WeatherNation meteorologists are keeping an eye on this situation. We’ll bring you the latest information as it becomes available.
