A look at the rain and wind impacts on Northern California. Plus a look at Hurricane Kathleen from 1976 and a discussion about alluvial fans. You don't get that every day!
7:39 "The Fujiwhara effect (Fujiwara effect, Fujiw(h)ara interaction, or binary interaction) is a phenomenon that occurs when two nearby cyclonic vortices move around each other and close the distance between the circulations of their corresponding low-pressure areas."
Thanks for scheduling the weekend weather updates - the SoCal picture is going to be tough. Hope that CALTRANS peremptorily closes the interstates - lost a CHP co-worker (and his partner) in the middle of the night to a bridge washout they couldn't see during a terrific rainstorm.
An excellent breakdown of the upcoming storm, really impressive usage of aerial imagery as it relates to excessive runoff in the deserts. I would like to add the possibility of debris flows since those mountains never see this type of orographic setup. Worried about those excessively rocky slopes cutting loose.
Hey Mark here in Plymouth ... Thank you for doing these morning briefing, I look forward to these! Thank you for sharing these and all the work you do!
The desert communities, especially in the Coachella valley, are really going to suffer I'm afraid. I hope local authorities are preparing for the worst.
As long as it doesn’t interrupt my beach volleyball games until after 12pm Sunday! Loving the overcast cool SoCal weather right now but we are all preparing for a deluge. Best CA weather channel on YT! Thanks Mark!
I live in San Diego and those alluvial fans are where they have flash floods. They have warning signs along the roads for flash flooding and people have been killed out there in the past from them. You did generally pronoun Ocotillo properly. Some people call it Ocotillo Wells. It is a very small town so I could see it getting completely wiped out. Thank you for keep us updated on this storm.
I used to live in Jacumba (at the top of the hill) and have friends in Ocotillo (at the bottom). I'm so glad Hurricane Kathleen was mentioned because people who have lived in the area for awhile certainly know what happened afterwards. These storms can be utterly devastating.
I’m in Southern Mexico at the moment and already experienced Hilary prior to her strengthening. However, my residence is in Yuma, AZ…. I remember Kathleen well in 1976.
Hi Mark, Found your channel thanks to Juan Brown's Blancolirio channel. I'm a San Diego resident, and the local station weather channels can't touch your report. Excellent content and presentation. This is very helpful. Thank you - will check in later today and through the weekend. I expect power outages, so will prepare accordingly.
Thanks for the updates Mark! I myself commute from Ontario to Palmdale monday afternoon on Hwy 138, but I may take a longer route just to avoid any flooding
Hey Mark! I would love some weather education videos from you on how certain weather systems work here in CA. Like how El Niño effects Tropical Storms, the Fujiwhara Effect or how the Pineapple Express, ArkStorms work specifically for California. It’s one thing to get generic information from Google, but way better coming from someone who we trust for our weather. Thanks for all you do!
Yikes. I have family in both San Diego and La Quinta. Should they evacuate ahead of this storm? Especially the family in La Quinta, because that is at the bottom of a huge drainage from the mountains around Palm Springs.
It was Hurricane Katherine in Sept 1976 that wiped out 90% of Fresno County's raisin crop.Fresno County is where 95% of the nation's raisin crop is. Fresno received .75 inch of rain. Most of the cotton crop in Fresno, Kings, Tulane & Kern counties was damaged or lost. 1976 was the beginning of a 2 year drought. I know I lived down there then.
Tropical storm is 45 mph. If there's wind damage from that, you've got a building standards problem . It a rain problem. Too bad you can't save any of the water.
This is what we deal with in the Negev desert in Israel. Flash flooding 40km away from a thunderstorm in a completely separate location with bright sunny skies.
I live in San Diego and we know that when the news says “its gunna be a big one” we dont believe them at all because it never comes and its NEVER as big as they say…….. and when they dont say anything THATS when we get hella rain. Better safe than sorry though.
