Strong North Pacific High + low pressure in Great Basin + strong winds aloft = Epic winds!

Strong wind ruled the west coast on March 12, 2019. Here is a visual summary of the causes and the results:
- Note the North Pacific High off the west coast.
- Look at how the NPH’s isobars stack up along the west coast creating strong NW wind.
- Check out the low-pressure zone in the Great Basin creating a strong pressure gradient.
- Note how the NW wind curves inland towards the low pressure in the Basin.
- Check out how many of the sensor in the San Francisco Bay Area have winds in the low 20’s to upper 30’s
- 3rd. Ave had peak average winds to 37 mph.
- And Southern California had sites with winds in the upper-teens to even mid 20’s.
- C St. in Ventura had average winds to 26 mph.
- A bit factor in the strong surface wind was the strong gusts to 40 mph just aloft over the Bay.
- And Southern California had similar winds aloft.
- On most days kites way outnumber windsurfers at 3rd. Ave. but not late Tuesday afternoon.
- An for a change the Gorge was at the bottom of wind totem pole excepts for Dougs that hit a respectable 29 mph.
