M6.5+ possible in highlighted areas near Eureka/ferndale, Geysers/Cobb, and longest line from Lake Isabella down past Mexico border (I am thinking west of Salton Sea to Mexicali). Watch is from time of this post to Saturday June 24 0000 UTC. See link for image.
I am opening this watch, with same area highlighted before, for a new time period from today to the 28th at 2300 UTC. M4 hit rio dell yesterday, and M3.5 in Banning. Could be surprise uptick with influence of new moon still and low pressure shifting.
Could just be due the coronal holes at this time, disaster app shows high number, and California is showing showing some higher activity along the white axis I drew on this image. Loma linda took a m3.2 recently with recent activity within what seems to be a radius of about 30KM. And, there are stacked quakes in Gilroy, and just ssw of Kettleman City. My eyes are on on the area around Loma Linda, Gilroy, and Kettleman city for a 24-36 hr period. M6+ potential in those spots with 30KM radius for each.

As the current so cal activity seems to continue, I am going to extend my watch for this area to July 8 0000 UTC. If large coronal holes persist, with low pressure developments that vary from slight convergence to coastal eddy, so cal may be more sensitive at this time. However, these lows appear weak overall. Still thinking M6+, but centering the watch on a 50km radius from Loma Linda.
July 9th- new watch for California. From time of this post to July 13th 0000 UTC. M6+ potential in highlighted area. From mammoth lakes area on east side of Sierra Nevada mountains to just south of the Salton sea.
