Bay Area: Midweek Weather Pause Before Weekend Rain
After recent heavy rainfall, San Jose and the wider Bay Area enjoy a brief, welcome dry spell. This midweek reprieve offers a chance to prepare, but it’s temporary. Forecasters track another significant system bringing renewed rainfall starting late Friday and continuing through the weekend. Bay Area locals should begin preparations.
A Brief, Welcome Interlude
Following recent storms, the Bay Area experiences brighter conditions with mild temperatures (50s-60s°F) and reduced rain chances. This is an ideal time to clear storm drains, secure outdoor items, or perform minor home repairs before the next wet period.
Despite the calm, ground saturation across San Jose and surrounding valleys remains high. Local creeks like Guadalupe and Stevens Creek are elevated. This means even moderate rain can rapidly increase runoff, elevating localized urban and small stream flooding risk. Saturation is a key factor for the weekend forecast.
Weekend Rain Returns: What to Expect
The current fair weather transitions late Friday as the next storm system approaches. Models indicate a moderate to strong system bringing widespread rain. Precipitation is projected to begin late Friday, intensify overnight, and persist through Saturday, potentially into Sunday morning.
Rainfall totals for San Jose and East Bay hills are anticipated at 1 to 2 inches over the weekend; higher elevations could see more. Rain will be steady, with periods of heavier downpours, especially Saturday. Wind gusts may also accompany the system, particularly near the coast.
Travel & Outdoor Impacts
Wet weather will impact weekend plans. Drivers should anticipate slick roadways and reduced visibility. Major routes like Highway 101, I-280, and Highways 85/87 in San Jose will likely see increased travel times and hydroplaning risks. Slow down, increase following distances, and use headlights.
Outdoor recreation might be best indoors. Hiking trails in the Santa Cruz Mountains and local parks could become muddy, slippery, and unsafe. Check event statuses as outdoor activities may be canceled.
Localized flooding remains a concern, especially in areas with drainage issues: low-lying intersections, underpasses, and streets near creeks. Remember: “Turn around, don’t drown.” Never drive or walk through flooded streets. Report flooding or downed trees to San Jose non-emergency services.

| Driving Conditions | Excellent, dry roads, good visibility | Slick, reduced visibility, potential for hydroplaning and delays |

Essential Preparedness Steps
As another rainy weekend approaches, proactive preparation is crucial for Bay Area locals:
- Home: Clear gutters, direct downspouts, secure outdoor items. Check for leaks.
- Vehicle: Verify tire tread/inflation. Test wipers/headlights. Keep full tank.
- Emergency Kit: Refresh home/car kits: flashlight, batteries, first-aid, food, water, charged power banks.
- Stay Informed: Monitor NWS/local news forecasts. Sign up for Santa Clara County alerts.
- Driving Safety: Drive cautiously. Slow down, maintain space, avoid sudden movements. Never drive through standing water.
- Power Outages: Have candles, flashlights, battery radio. Report to PG&E.
- Property Protection: If flood-prone, have sandbags. San Jose often provides distribution points.
Be aware of local flood zones: near creeks, low-lying neighborhoods, underpasses. Stay vigilant and follow advisories.
