Flood Watch

Redondo Beach, WA

Day 1: 2024-10-16

CATEGORY 3

WHAT Minor coastal flooding possible due to high tides.

WHEN From 3:00 PM to 4:30 PM PST on October 16th.

IMPACTS Minor flooding of low-lying areas near shorelines and vulnerable roadways. Isolated road closures are possible.

ADDITIONAL DETAILS...

On October 16th, a high tide is expected at 3:30 PM with a projected tide height of approximately 20.00 feet. The barometric pressure during this time is forecasted to be around 1024.45 hPa, which is higher than pressures associated with severe flooding events in the past. Wind speeds are expected to be low, around 5 mph coming from the west-northwest. NOAA's flood likelihood is low, with a likelihood percent of 0.1% and a distance to the flood threshold of -1.3 meters. Compared to the historical Category 3 event on 12/27/2023, where the tide height was 17.46 feet and barometric pressure was 1006.1 hPa, the current conditions show a higher tide but significantly higher pressure, suggesting a similar Category 3 risk level without major concerns.

Day 2: 2024-10-17

CATEGORY 3

WHAT Minor coastal flooding possible due to high tides.

WHEN From 4:00 PM to 5:30 PM PST on October 17th.

IMPACTS Minor flooding of low-lying coastal areas and waterfront parks. Some roads may experience water coverage.

ADDITIONAL DETAILS...

On October 17th, the high tide is expected at 4:00 PM with an anticipated tide height of approximately 20.14 feet. The barometric pressure is forecasted to be around 1018.89 hPa, still higher than the pressures during historical severe flooding events. Winds are expected to be very light, about 4 mph from the north. NOAA indicates a low flood likelihood of 0.4%, with a distance to the flood threshold of -1.02 meters. While the tide height is slightly higher than the historical Category 3 event, the higher barometric pressure and low wind speeds maintain the flood risk at Category 3, indicating conditions worth monitoring but unlikely to cause significant impact.

Day 3: 2024-10-18

CATEGORY 3

WHAT Minor coastal flooding possible due to high tides.

WHEN From 4:30 PM to 6:00 PM PST on October 18th.

IMPACTS Minor inundation of low-lying areas along the coast. Few road closures or disruptions possible in susceptible locations.

ADDITIONAL DETAILS...

On October 18th, a high tide is anticipated at 4:36 PM with a tide height of approximately 20.07 feet. The barometric pressure is forecasted to be notably high at around 1027.40 hPa, indicating stable atmospheric conditions. Wind speeds are expected to be low, approximately 7 mph from the south. NOAA's flood likelihood remains low at 0.1%, with a distance to the flood threshold of -1.22 meters. Comparing these conditions to past events, such as the historical Category 3 event, the combination of a high tide height with high barometric pressure and low wind speeds suggests a continued Category 3 risk level, implying minor concerns without expectations of major flooding.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.
