Parking tickets. Uber drivers who want your phone number. Being trapped in a corner by the Girl You Wish You Hadn't Started a Conversation With at a Party. Rain on Halloween weekend. This is the stuff of Angeleno nightmares.

A storm system — possibly two — will likely bring the last part of that nightmare to life. An “early-season storm system” is expected to strike as early as this afternoon. And it could possibly last into Friday, according to the National Weather Service.

The first front will pass through Greater Los Angeles Thursday night through Friday morning and possibly beyond, forecasters say. There will be a chance of thunderstorms and snow at the “highest peaks” in local mountains, according to the NWS.

This first front will be relatively warm for a storm. There will be heavy rain at times, forecasters believe, with as much as a half inch per hour in some areas.

“There will be the potential for moderate to heavy rainfall and thunderstorms as the storm taps into subtropical moisture and the remnant moisture from Hurricane Seymour,” according to the weather service. “San Luis Obispo and Santa Barbara counties will have the best chance of heavy rain and thunderstorms, but there is also the potential in Ventura and Los Angeles counties. Flash flooding, along with mud and debris flows, will be a concern with any thunderstorms or heavy rain, especially for recent burn areas.”

Forecasters are predicting as much as an inch of rain total in the L.A. Basin, perhaps as many as two in some foothill areas. There is a slight chance of leftover rain again Saturday, with another front moving in Sunday that should slide above a drying-out Southern California, they say.

The Auto Club of Southern California is urging drivers to be extra careful as the rain hits today and tomorrow. “This storm is expected to produce a lot of rain, so we’re reminding motorists that wet roads and cooler weather combine to significantly increase crash risk,” says the club's traffic safety manager, Anita Lorz Villagrana. “As best they can, drivers should scan the roadways, avoid road debris and look out for disabled vehicles in reduced-visibility conditions.”

The big question, of course, is what the weather will look like on Monday, Halloween. Forecasters say it should be good. “High pressure begins to ridge across the region by Halloween with drier and warmer conditions rebounding across the state,” according to the NWS.
