Swiftly moving rain showers are on their way to the Bay Area<\/a>, bringing chances of thunderstorms, gusty winds and localized flooding in their wake.<\/p>\n

Dylan Flynn, a meteorologist for the National Weather Service\u2019s Bay Area office, told SFGATE the jet stream is the culprit. The narrow band of strong wind in the upper atmosphere typically moves west or east, but on Sunday was pushing a deep low pressure system from the Pacific Northwest \u201cstraight south toward us.\u201d The storm is expected to hit the North Bay as soon as Monday morning.<\/p>\n

\u201cIt\u2019s moving really fast,\u201d Flynn said over the phone. \u201cIt\u2019ll only be an hour before it gets to San Francisco, and another hour before it gets to San Jose.\u201d\u00a0<\/p>\n

The rain is forecast to persist through the afternoon, getting \u201cheavy at times\u201d before clearing out by midnight, he continued. Scattered showers will likely linger through most of the day Tuesday, delivering roughly half of an inch of rain in the North Bay and closer to an inch in the rest of the Bay Area. Flynn said the NWS doesn\u2019t have a weather station in the Santa Lucia Mountains and therefore can\u2019t offer a precise estimate of rainfall there, but noted they\u2019re likely to get the heaviest precipitation with as much as three inches of rain.<\/p>\n

Flynn said the storm sticks out for two reasons: not only is it coming earlier than usual for October, which is usually still coming out of the dry season, but it\u2019s also particularly strong.<\/p>\n

\u201cIt\u2019s roughly an October’s worth of rain we\u2019re expecting in two days,\u201d he said. \u201cWe usually don\u2019t get this much this fast.\u201d<\/p>\n

0.81 inches of rain are forecast for San Francisco \u2013 by comparison, the city usually gets 0.94 inches for the month. San Jose is also expected to receive twice as much rain than it sees in a typical October, with 0.93 inches of rain expected to fall this week compared to its usual 0.53 inches in a month, according to weather service records.<\/p>\n

20 to 30% chances of thunderstorms are forecast across most of most of the Bay Area on Monday, decreasing to 10 to 20% chances more focused to the South Bay to the Central Coast on Tuesday. No severe storm criteria recognized by the weather service \u2014 that includes damaging winds of 60 mph, hail over one inch, or tornadoes \u2014 are expected in this system. However, Flynn said smaller hail could pile up on roadways, \u201cmaking driving conditions really dangerous.\u201d 30 to 40 mph gusts are possible, and the rain rate is also much higher during a thunderstorm.<\/p>\n

\u201cOne inch of rain can\u2019t cause widespread flooding,\u201d he said, \u201cbut if you\u2019re right underneath it, it can cause flash flooding in urban areas or those with more pavement, which is much less permeable than soil.\u201d<\/p>\n

In spite of the hazards, the storm will also bring its fair share of beneficial impacts. Flynn said the system is expected to put a damper on fire season<\/a>, if not ending it completely on a statewide level. The rainfall will also build reservoirs and fill rivers that are running low after the dry season.<\/p>\n

Conditions are expected to clear up by Wednesday.
