Forecast note (as of Nov 5, 2026): NOAA's Climate Prediction Center has an El Niño Advisory in effect and expects a strong-to-very strong El Niño through January–March 2027, with chances remaining above 83% (CPC ENSO discussion, Oct 8, 2026; CPC status update, Nov 2, 2026). The National Weather Service in Los Angeles (AFD 12:43 PM PST Nov 5) keeps dry offshore weather through about Wednesday, a chance of light rain Thursday, Nov 12, then wet and unsettled weather from about Friday, Nov 13 into that weekend, with ensembles showing decent chances of widespread 1+ inch totals though timing and amounts remain uncertain (NWS Los Angeles AFD). NWS San Diego likewise flags a large trough late next week with substantial rain possible but low confidence in the details (NWS San Diego AFD). El Niño raises the odds of a wet winter, but it doesn't guarantee one. Check weather.gov/lox before each storm.
Save this to your phone. When the rain is coming down sideways at 2 a.m., you won't want to read an article. You'll want a list.
Water and electricity can mix safely only when you set them up correctly. Here's how I set up every pump:
Take photos before you clean up. Dry everything within 24 to 48 hours. EPA flood-cleanup guidance stresses drying wet materials within 24 to 48 hours (EPA). If that's more than you can handle, our water damage restoration team can help. Local pages: Encino, Tarzana, Calabasas.

Before the El Niño rains and the holidays, get a sewer mainline snake plus camera inspection for $99. Mention "Gio's $99 special" when you call or text 855-840-7800. Mention the special when booking; valid through 12/31/2026. See Gio's $99 Special.
Test your pump and GFCI outlet, lay the hose out to the curb, clear your drains, and move valuables off the floor.
Every hour or two during heavy rain, unless you have an automatic float switch.
No. Unplug it first, and never touch the pump or cord while you're standing in water.
When water reaches outlets or the electrical panel, when it smells like sewage, or when it rises faster than you can pump it. Call or text 855-840-7800, 24/7.
