An Extreme Heat Warning continues for the Yuma area and most of western Imperial County through 8 pm MST/PDT tonight. Afternoon highs are expected to reach 102°-105°F, or around 8-13 degrees above normal.
The remnants of Tropical Cyclone Rachel and a Pacific low pressure system will combine to produce windy conditions across much of the area on Sunday morning and afternoon. Wind gusts upwards of 30-55 mph are expected. A Wind Advisory has been issued for much of the area for Sunday morning and afternoon. Portions of SE CA and SW AZ are under the advisory from 2am-5pm MST/PDT on Sunday and south-central AZ is under the advisory from 8am-5pm MST on Sunday.
A low pressure system will combine with the remnants of Tropical Cyclone Rachel bringing increased rain chances and breezy to windy conditions to the region this weekend. Isolated thunderstorms and localized heavy rainfall leading to flash flooding is possible. Additionally strong gusty winds are expected and could lead to areas of blowing dust.
The deep low pressure system that will be over the West Coast this weekend will eventually move inland early next week. On Tuesday it will move through our region bringing additional chances for showers, mainly to south-central AZ.
Well above normal temperatures will continue today resulting in areas of moderate to locally major HeatRisk across the lower deserts. Afternoon highs will be around 10 degrees above normal and near daily records across the western deserts. Temperatures will then nosedive to well below normal by the beginning of next week. Temperatures will then gradually warm during the latter half of the workweek.
