Flash Flood Watches issued: Ash, mud and debris flows possible for the burn scars in California

Flash Flood Watches are in effect in Northern California ahead of rain expected to develop along the US West Coast Wednesday morning, November 21, 2018. After that, a parade of storms is expected to march through the weekend. Meanwhile, Air Quality Alerts are expected to remain in effect over parts of Southern California until the fires are extinguished. 

A deep upper-level trough will move onshore over the West Coast early Wednesday, November 21 into Thursday morning, November 22 (Thanksgiving), NWS forecaster Ziegenfelder said November 20.

Rain will develop along the West Coast early Wednesday morning and expand inland to the Northern Intermountain Region/Great Basin by Thanksgiving morning.

Flash Flood Watch for the burn scars is in effect Wednesday afternoon through Friday morning, NWS office in Sacramento said November 20.

Ash, mud and debris flows is possible for the burn scars.

"There is a marginal with embedded slight risk of excessive rainfall over California from Wednesday morning into Thursday morning," Ziegenfelder added. 

"As the trough moves inland the snow levels will lower over the Cascades and the Sierras. Snow will begin over the higher elevations of the Cascades and Sierras by Wednesday afternoon continuing into Thursday morning. Overnight Wednesday, snow will develop over parts of Northern California and the Southern Cascades."

"After the arrival of Wednesday’s rain, it’s going to be a parade of storms through the weekend as several more waves of moisture and energy swing through," Weather Nation meteorologist Merry Matthews said.

"It is important to stay up-to-date to changes with this forecast. The timing of this event makes for higher impacts as more people frequent the highways and interstates for the Holidays. Debris flows, mudslides can shut down area roads quickly so be sure to plan your routes accordingly," she concludes.

Now therefore, what do I have here," declares the Lord, "seeing that my people have been taken away without cause?" Those who rule over them howl and my name is continually blasphemed all day long! Isaiah 45:7" At the time that you have took this land of Israel that you have called the USA. did you not thank that this time of 11:52 AM 9/11/ 7/26/18 will never come suddenly on you all! For you knew that this land of milk and honey was not truly the one that God had in mind to keep forever didn't you Nations of the earth? So now a decree by God has been sent out; that you and all of your children will be rooted out of this earth forever!
You who were for so long at ease are just a bunch of wishful thinkers, you along with that dark star that you all like to worship are now seeing that our God is not one to be mocked! Amos 6:1 Jeremiah 48:11 Ezekiel 16:49 Zechariah 1:15
