The Firefighters in Washington State, who are currently working to contain what may prove to be the biggest wildfire in the state's history, just got some good news from weather forecasters.

Heavy rainfall and thunderstorms are expected over the next few days across the state, with the potential for record-breaking rainfall covering certain parts of the state's western half.

USA Today is reporting that the National Weather Service has also issued a flash flood warning through this evening in response to the heavy amounts of rainfall that's expected.

Officials in charge of the firefighting effort are hopeful the coming rain can help contain the Carlton Complex Fire near central Washington. So far the fire has burned approximately 390 square miles and, according to firefighters is about 16% contained.

Casualties include one death and nearly 150 homes, and 1,200 additional residences are estimated to have been evacuated across 12 different cities.

President Obama signed an official federal emergency declaration today that covers the regions affected by the blaze. The move gives FEMA and the Department of Homeland Security the authority to organize a disaster relief effort, as well as supply the necessary resources to local and state agencies.

According to the Washington Department of Natural resources, the current effort to combat the wildfires has already cost the state $25 million, $6 million more than the annual budget allocated for fire services this year.

Department deputy supervisor Mary Verner is expressing concern over the budget, saying that "The numbers so far are staggering. This is still early in the season that is supposed to last through mid-October."

That cost does not take into account the other smaller fires across the state either.

"Looking forward, we have to always worry about whether or not we will have enough money in the state coffers to pay for the fires that actually occurred," said Verner. "That will far exceed the $19 million available.

While at a Seattle fundraiser earlier this week, President Obama attributed Washington's current wildfires and other recent blazes to climate change.

"A lot of it has to do with drought, a lot of it has to do with changing precipitation patterns, and a lot of that has to do with climate change," Obama said.
