250+ Cloud to Ground Strikes In Metro Area

May 25, 2012

Here’s the final lightning map for this evening…

If you take a line from about St. Helens over to Amboy, then count all the strikes from there south to about a Newberg-Canby line, you get a bit over 250 lightning strikes this evening; quite impressive.

More interesting is the location…almost all strikes were west of I-5 & Hwy. 217 in Oregon and north of I-84.  Downtown Portland and areas straight south and east didn’t see any strikes.


All Clear For Fireworks; But Stormy In Salem

May 25, 2012

Rain has ended in most of Portland and the showers continue to head south.  Fireworks viewing (at 9:55pm) will be dry downtown.

But here’s the latest image from the mid-Valley…wet!

These storms will continue to head south and die down over the next hour or so.

Lightning Strikes So Far…

May 25, 2012

Lightning strike map so far this afternoon. None IN the metro area, but lots in the past hour north and east of Vancouver & Camas. A few in the Coast Range too. This only detects cloud-ground or ground-cloud strikes.

Looks like our RPM was right on, thunderstorms have developed north of Battle Ground and heading down towards Camas. Any of us could see one in the next 3 hours. Nice looking clouds to the north of the metro area too!
