Contained by 65%, the "Camp Fire" is not expected to be fully controlled until the end of the month, said the California fire service, which deployed some 5,000 men and 28 helicopters to combat it.
Resurface from the ashes
Survivors and relatives of the victims gathered on Sunday at the First Christian Church in the neighboring town of Chico for a vigil.
"We will rise from the ashes", was a poster on the altar.
Thousands of neighbors managed to flee the flames took refuge in churches and tents.
The National Weather Service indicated that low levels of humidity and winds will prevail in much of California on Monday, but indicated that these conditions could change.
The forecast for the Paradise area forecasts rain Tuesday night and heavy rains on Wednesday, a day before the Thanksgiving celebration.
Sad to see
With a serious face and no mask despite the smoke that covers the region, Trump noted in Paradise the extent of the disaster, accompanied by the mayor of Paradise, Jody Jones.
"It's sad to see," Trump said after spending about 20 minutes in a mobile home camp where only one national flag added some color to an ash landscape.
Forest management
The president reiterated his claim that California has made a terrible forest management, which he blames for the fires.
"I'm determined to make sure this is all clean and protected, (we must) take care of the forest, it's very important," Trump said.
Days before, he had threatened to cut federal funds due to the alleged "poor forest management" of the California authorities, forgetting that the forests are mostly under federal control.
Brian Rice, president of the California Association of Professional Firefighters, had called Trump's statements "misinformed," noting that the federal government had cut the budget for forest management.
The Congress approved a budget of 2,000 million dollars for the fight against forest fires in fiscal year 2018.
