The officer was killed last night when he was trapped between a loose boat and rocks near the Green Pleasure Pier.
Windyty is one of those websites where you can lose a lot of time just staring and trying new views.

It was very nice having a couple of episodes of soft rain fall on my head (and my yard) over the weekend. But despite the isolated newsworthy pummeling over and just below the San Gabriels, this was not much of a rain event.

Credit for the headline to the High Country News, which notes that "with each passing day it seems more certain: 2014 is going to be an El Niño year, and probably a big one."

Since it looks as if the SoCal fire season is going to be long and mean, scientist-blogger Grace Peng offers a primer on the physics of flames and wind here. Plus: Reuters photographer Jonathan Alcorn on an eerie night at the Camarillo Springs fire.
The wildfire that began near Camarillo Springs Road and U.S. 101 spread to 28,000 acres on Friday, but firefighters kept the flames from engulfing any homes for a second day. Residents fled several neighborhoods, however, as the fire jumped ridges and moved toward communities such as Hidden Valley.
Brush conditions around Camarillo are like October, fire officials say — and it's only May. More than 6,500 acres have scorched, forcing evacuations, but no homes have been destroyed. Burned agricultural buildings in the strawberry fields near Cal State Channel Islands have raised concerns about toxic smoke.

Today's usual afternoon thundershowers over the San Gabriels and the high desert smushed down into the basin this time, drenching places like Altadena and Studio City in some pretty heavy rain.

Fun diversion for many, judging by social media, unless you were caught in the places where summer t-storms turn into flash floods.
John Rabe of KPCC enticed me out to Northridge on Wednesday for an "Off-Ramp" story, and since it was midday in the West Valley, in the middle of a heat wave, and Rabe's an intrepid reporter slash radio host, he brought along the makings of a classic journalism experiment. The temperature was a few notches over 100, but was it hot enough to cook an egg? Find out inside.
