SAN FRANCISCO (KRON) — Most parts of the San Francisco Bay Area have moved out of the ‘exceptional’ drought category on Thursday, according to KRON4 Meteorologist John Shrable.

Most in the region moved to the ‘severe’ category, although parts of the East Bay remain in the ‘extreme.’

The Bay Area has seen multiple rainstorms that have helped the drought issue, including a severe storm back in October that prompted evacuations, flooding, power outages, etc.

National Weather Service Meteorologist Sean Miller says while the rainfall is needed, sometimes it rains too much at once.

“We still have to make up for how dry it’s been over the last couple of years or so,” Miller said. “We really need keep that water flowing through the remainder of this winter season so we can help to fill up the reservoirs.”

According to the U.S. Drought Monitor, the levels of drought from least to most severe goes in this order: abnormal, moderate, severe, extreme, and exceptional.

Most of the Bay Area improved two levels from ‘exceptional’ to ‘severe’ drought, dating back from Oct. 1 to Thursday.

There has also been a drought improvement statewide.

The exceptional drought category, as defined by the U.S. Drought Monitor, includes air quality, water shortages, and wildfire being affected.

“Poor air quality affects health; greenhouse gas emissions increase as hydropower production decreases; West Nile Virus outbreaks rise.”

“Fire season is very costly; number of fires and area burned are extensive.”

“Water shortages are widespread; surface water is depleted; federal irrigation water deliveries are extremely low; junior water rights are curtailed; water prices are extremely high; wells are dry, more and deeper wells are drilled; water quality is poor;”
