Day 2: November 18, 2024

CATEGORY 3

WHAT: Minor coastal flooding possible. Slight inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.

WHEN: Highest risk period during the morning high tide, around 7:00 AM to 10:00 AM PST.

Wind speeds decrease to 6 mph from the south, reducing wind-related impacts. NOAA's flood likelihood is high at 5.2%, but this is still lower than historical Category 3 events. Despite the NOAA's higher likelihood rating, the consistently high barometric pressure and lower wind speeds support maintaining the flood risk at Category 3.

Day 3: November 19, 2024

CATEGORY 3

WHAT: Minor coastal flooding possible. Slight inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.

WHEN: From morning to late morning, around 7:30 AM to 10:30 AM PST.

IMPACTS: Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.

ADDITIONAL DETAILS...

The barometric pressure slightly decreases to 1021.25 hPa during the high tide at 8:18 AM but remains above critical levels associated with severe flooding. Tide heights reach about 20.4 feet. Wind speeds are low, approximately 4 mph, with wind directions shifting from the south to east-northeast. NOAA's flood likelihood is low at 2.6%, indicating minimal risk. The combination of these factors results in a continued flood risk assessment of Category 3.
