A West-to-East Storm Could Affect Weather Across Most of the Country

A massive storm is going to travel across the country this week, persisting through Election Day. It will unleash rain and snow in over 35 states. Here is a look at what you can expect as this cross-country storm travels from west to east.

Cross-Country Storm Will Impact Dozens of States

A strengthening El Niño is being blamed for a monster storm that will get its start in the southwestern U.S. before moving to the east. Rain began falling in Arizona on Friday ahead of the core of the storm, signaling what is ahead.

It is rare to see rain on Halloween in Southern California, but that might change this year as the storm ramps up just in time for the holiday. Moderate to heavy rain is in the forecast on Saturday for this part of the Golden State, threatening trick-or-treating plans in cities such as Los Angeles and San Diego. 

There have only been nine Halloweens with measurable rain since 1850 in San Diego. You have to go back to 1987 to find the last time that rain impacted the holiday in this metro area.
