Weather alert for showers in Bay Area Wednesday evening – winds gusting up to 40 mph
San Francisco Peninsula Coast, Santa Cruz Mountains and Santa Clara Valley Including San Jose are under a weather alert for showers by the National Weather Service on Wednesday at 6:58 p.m. The alert is in effect until 7:30 p.m.
Wind gusts of up to 40 mph and pea-sized hail (0.25 inches) are probable.
“At 6:58 p.m., Doppler radar tracked a shower 10 miles west of Boulder Creek, or 18 miles northwest of Santa Cruz, moving northeast at 20 mph,” according to the NWS San Francisco CA. “Waterspouts can easily overturn boats and create locally hazardous waters. Gusty winds could knock down tree limbs and blow around unsecured objects. Minor damage to outdoor objects is possible.”
Locations impacted by the alert include Palo Alto, Cupertino, Saratoga, Woodside, Boulder Creek and Portola Valley.
The NWS said, “Monitor the weather situation closely and be alert for threatening weather conditions. Torrential rainfall is also occurring with this storm and may lead to flash flooding. Do not drive your vehicle through flooded roadways. Showers will be capable of producing large quantities of accumulating hail. This may result in slick and hazardous driving conditions. Slow down and use caution if driving.”
Rainy day rules: How to stay safe in heavy precipitation
When heavy rain sets in, the risk of flooding and hazardous driving conditions rises. Whether it’s prolonged rainfall or rapid runoff, being prepared is essential. Here are some valuable safety tips from the NWS to ensure you stay safe in heavy rain:
Beware of rapid water flow:
- During heavy rain, avoid playing near culverts or drainage ditches, where swift-moving water can pose a serious risk.
Maintain safe driving distances:
- The two-second rule for following distance is your ally in heavy rain. Extend it to four seconds to ensure safe spacing in adverse conditions.
Slow down and drive with care:
- On wet roads, reducing your speed is crucial. Ease off the accelerator gradually and avoid abrupt braking to prevent skidding.
Choose your lane wisely:
- Stick to the middle lanes to minimize the risk of hydroplaning. Outer lanes are more prone to accumulating water.
Visibility matters:
- Enhance your visibility in heavy rain by turning on your headlights. Watch out for vehicles in blind spots, as rain-smeared windows can obscure them.
Watch out for slippery roads:
- The first half-hour of rain is when roads are slickest due to a mix of rain, grime, and oil. Exercise heightened caution during this period.
Keep a safe distance from large vehicles:
- Large trucks and buses can reduce your visibility with tire spray. Avoid tailgating and pass with caution.
Mind your windshield wipers:
Overloaded wiper blades can hinder visibility. If rain severely limits your sight, pull over and wait for conditions to improve. Seek refuge at rest areas or protected spots. When stopping roadside, position your vehicle as far off the road as possible, ideally beyond guardrails. Keep your headlights on and activate emergency flashers to alert other drivers.
In the face of heavy rain, these precautions can make a significant difference in ensuring your safety on the road. Remember to stay informed about weather conditions and heed guidance from local authorities for a secure journey.
