The rain caused some confusion for drivers in North Fresno after a transformer exploded, leaving about 2500 PG&E customers in the dark.
The brief power outage forced people at this restaurant to eat by candlelight and left some would-be diners disappointed.
"Yeah, actually I am. You know, I was really in the mood for Chinese and I'm just going to have to go someplace else."
In Clovis, people like Josh Richards filled sandbags to prevent flooding in their homes. The city is offering residents up to 10 bags a piece.
By Sunday night, several people had already taken advantage of the free service.
"Why are you picking up bags tonight?"
"I've just got to block garage door a little bit. It's going in a little bit, nothing too serious. And it's real sturdy against the current, so it's nice."
In Northeast Fresno, firefighters were also busy preparing for this week's series of storms.
Fresno County equipped with water rescue supplies. Normally, the equipment is only used during the summer months.
But with Storm Warn 30 predicting at least 4 inches of rain in most places throughout the valley, firefighters predict they have a busy week ahead.
"If a mutual call comes in for a water rescue or a confined space or heavy duty rescue due to mudslides or swelling of the rivers, we would automatically dispatch our personnel out there from the rescue team."
The equipment you just saw there could easily be deployed anywhere throughout the state in case of water-related emergencies.
There's more rain ahead this week, which means slow down when you're driving and if you live in Fresno, report any flooding issues to city officials by calling 621-CITY.
