Coastal flood advisory in place for Bay Area Shorelines from Thursday to Sunday

Northern Monterey Bay and Southern Monterey Bay and Big Sur Coast as well as San Francisco County are included in a coastal flood advisory issued by the National Weather Service on Wednesday at 8:07 p.m. The advisory is valid from Thursday 6 a.m. until Sunday Feb. 1, at noon.

“Up to 1.4 ft of inundation above ground level is possible in low-lying areas near shorelines and tidal waterways,” can be expected according to the NWS San Francisco CA. “At the San Francisco tidal gauge, high tide is expected to be: 1.2 ft above normal (7.02 ft MLLW) at 7:34 a.m. Thursday 1/29, 1.1 ft above normal (6.98 ft MLLW) at 8:34 a.m. Friday 1/30, 1.4 ft above normal (7.24 ft MLLW) at 9:30 a.m. Saturday 1/31, 1.3 ft above normal (7.16 ft MLLW) at 10:22 a.m. Sunday 2/1. These predictions include up to 0.4 ft of storm surge that will enhance the astronomical tide and flooding threat. High tide timing varies up to 90 minutes earlier or later along the Pacific Coast and through the San Francisco Bay, respectively.”

“Flooding of lots, parks, and roads with only isolated road closures expected. Dangerous conditions are forecast along the shoreline. Hazards include sneaker waves, strong rip currents, and large breaking waves,” according to the NWS. “If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property. Stay off of jetties, piers, rocks, and other waterside infrastructure. Remain out of the water to avoid hazardous surf and NEVER turn your back on the ocean.”

Deciphering advisories, watches, and warnings: Understanding weather alerts

• Flash flood warning: Take action!

A flash flood warning is issued when a flash flood is either imminent or already occurring. In flood-prone areas, it’s crucial to move immediately to higher ground. A flash flood is a sudden and violent inundation that can develop within minutes to hours, and it can even happen in areas not currently experiencing rainfall.

• Flood warning: Take action!

A flood warning is issued when flooding is imminent or occurring.

• Flood advisory: Be aware:

A flood advisory is released when flooding is not expected to reach a severity level necessitating a warning. Nonetheless, it can still cause considerable inconvenience and, without exercising caution, potentially lead to situations that threaten life and/or property.

• Flood watch: Be prepared:

A flood watch is issued when conditions are favorable for flooding. It doesn’t guarantee that flooding will occur, but it signifies that the possibility exists.

Staying safe during a flood: Recommendations from the NWS

In flood-prone regions or while camping in low-lying areas, understanding and following the NWS flood safety guidelines can be a lifesaver:

Seek higher ground:

If you’re in a flood-prone area, or if you’re camping in a low-lying spot, move to higher ground as a first step.

Adhere to evacuation orders:

If local authorities issue an evacuation order, heed it promptly. Prior to leaving, secure your home by locking it.

Disconnect utilities and appliances:

If time allows, disconnect your utilities and appliances. This reduces the risk of electrical hazards during flooding.

Steer clear of flooded basements and submerged areas:

Steer clear of basements or rooms where water has submerged electrical outlets or cords. This helps prevent electrical accidents.

Evacuate promptly for safety:

If you notice sparks or hear buzzing, crackling, snapping, or popping sounds, evacuate without delay. Do not enter water that may carry an electrical charge.

Refrain from walking in floodwaters:

Never attempt to walk through floodwaters, even if they appear shallow. Just 6 inches of fast-moving water can forcefully sweep you off your feet.

Seek high ground if trapped:

In the event you become trapped by moving water, make your way to the highest point available and contact emergency services by calling 911.

When heavy rain occurs, there is a potential for flooding, particularly in areas that are low-lying or prone to floods. It is crucial to never drive through water on the road, even if it appears shallow. According to the NWS, as little as 12 inches of fast-flowing water can carry away most vehicles. Prioritize your safety by staying informed and prepared.
