A bonafide shower was reported along the San Diego (405) Freeway corridor shortly before sunrise. Any rain is welcomed, since the Southland just suffered through its driest season on record, with only 3.21 inches between July 1, 2006 and the first of the month. “It happens, but it is fairly rare,” Bruno said, adding that monsoonal moisture typically starts streaming in front the south around midsummer, bringing the prospect of thunderstorms. The most rain fell in the mountains, but only a fraction of an inch. The Antelope Valley got about a hundreth of an inch, Bruno said. The record rainfall for the date in downtown Los Angeles is 0.08 of an inch, set in 1986, he said, adding that the average for July is 0.01 of an inch. Rain. Imagine that. Well, it is not enough to quench parched hillsides, but a rare summer rain did fall across most of the Los Angeles basin overnight and this morning and a 20 percent chance of rain or thundershowers is forecast for today. “A few areas may get lucky and few hundreths of an inch,” said Meteorologist Dave Bruno of the National Weather Service in Oxnard. In general, it doesn’t really rain in July. “There are several days in the month that it’s never rained” in about 130 years of record-keeping, Bruno said. The most it has ever rain in July is 0.24 of an inch, and that was in 1886, he said. Big raindrops first started hitting the streets last night, and light showers were reported around the region overnight, possibly contributing to an accident in which a vehicle crashed into a Starbucks in Sherman Oaks.160Want local news?Sign up for the Localist and stay informed Something went wrong.
