On this day in 2004, a large winter storm brought a month's worth of record rainfall in a single day in many parts of Orange County and drenched much of Southern California. For the following two weeks, the lower elevations at Orange County saw 2 to 8 total inches of rainfall.

Things to do

Give yourself a high-five because you made it through the work week. Looking to several ways to kick off the weekend? How about checking out a comedy show:

  • Awkward Sex… and the City: Get ready to laugh at bedroom exploits as Awkward Sex… and the City makes its Los Angeles debut this weekend. Comedians share their awkward, intimate tales about their sex lives while breaking barriers about sex and dating. The show aims to take on taboo subjects while creating a safe space for all people to feel seen and heard.
  • There's still time to do some basic, spooky season activities this month. How To L.A. has you covered on where to enjoy your pumpkin spice latte, basic-girl autumn activities.
  • And if you were part of the Great Shake Out, now might be a good time to start prepping for the Big One. My colleague Jacob Margolis has this handy, low-stress guide to help.

Check out our full list of things to do this weekend.

At LAist, we believe in journalism without censorship and the right of a free press to speak truth to those in power. Our hard-hitting watchdog reporting on local government, climate, and the ongoing housing and homelessness crisis is trustworthy, independent and freely accessible to everyone thanks to the support of readers like you.

But the game has changed: Congress voted to eliminate funding for public media across the country. Here at LAist that means a loss of $1.7 million in our budget every year. We want to assure you that despite growing threats to free press and free speech, LAist will remain a voice you know and trust. Speaking frankly, the amount of reader support we receive will help determine how strong of a newsroom we are going forward to cover the important news in our community.

We’re asking you to stand up for independent reporting that will not be silenced. With more individuals like you supporting this public service, we can continue to provide essential coverage for Southern Californians that you can’t find anywhere else. Become a monthly member today to help sustain this mission.

Thank you for your generous support and belief in the value of independent news.
