Mike Smith is a meteorologist with the national Weather Service in Sacramento.
"Well, obviously it's a over a once in a 100 year event, so it's fairly rare," he says.
Smith says Sacramento is also likely to see a record high temperature today -- at 70 degrees. The old record was 69.
"Typically this time of year in Sacramento, we get right around the mid 50s and we're expecting a high today of 70s so that's about 15 degrees above normal," Smith says. "Some places in the northern valley will be pushing about 20 degrees above normal for this time of year."
Record summer heat has increased fire risk in California and the Western U.S. as drought conditions expand.
Statewide water conservation exceeded the mandatory goal in May and Sacramento reduced water use 40 percent.
In the fourth year of drought in California, sales and use of "safe and sane" fireworks are restricted in some areas, allowed in others.
A California Assembly committee will hear a bill Wednesday that would allow water districts to impose taxes on any business, industry or person who wastes water.
The drought can be blamed for a number of problems and the latest is a major decline in the duck population. A new survey shows lack of rain has led to poor habitats.
