WHAT Minor coastal flooding expected. Possible inundation of up to 1 foot above ground level near shorelines and low-lying areas.
*WHEN From 6:00 PM to 11:59 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure is significantly higher than the threshold that indicates severe weather conditions and potential flooding. However, the high tide at 6:00 PM with a pressure of 1018.22998046875 hPa and another high tide at 9:12 PM with a pressure of 1019.02001953125 hPa, combined with the historical data, suggests that there is a risk for minor coastal flooding. The NOAA Flood Likelihood for this date is low, which aligns with the current assessment.

WHAT Coastal flooding likely, with potential for some property damage in vulnerable areas.
WHEN From 3:00 PM to 11:59 PM PST.
IMPACTS Flooding of roads, parks, and low-lying infrastructure expected. Some property damage possible due to water inundation.
The barometric pressure is lower on this day, with readings of 1008.9099731445312 hPa and 1009.7899780273438 hPa during high tides, which is closer to the historical events that caused more significant flooding. The NOAA Flood Likelihood remains low; however, the combination of lower pressure and high tide levels warrants a higher flood category rating.
CATEGORY 5
WHAT Significant coastal flooding expected with a high likelihood of property damage.
WHEN From early morning around 7:36 AM to late evening around 11:18 PM PST.
IMPACTS Major flooding of residential and commercial areas near the coast is likely. Extensive road closures and damage to infrastructure are possible.
The barometric pressure drops further on this day to readings of 1004.489990234375 hPa during both high tides, which is very close to the Category 5 event from historical data. The tide levels are also expected to be high throughout the day. Given these factors and the historical comparison, there is a significant risk for extensive flooding similar to the Category 5 event on 12/27/2022.
