Flood Watch

Redondo Beach, WA

Day 1: 2024-11-14

CATEGORY 3

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

WHEN From 14:00 PST to 15:00 PST.

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

ADDITIONAL DETAILS...

On November 14, 2024, a high tide is expected at 14:42 PST with a tide height of approximately 20.32 feet. The barometric pressure at this time is forecasted to be 1023.43 hPa, which is significantly higher than pressures recorded during historical severe flood events (e.g., 978.4 hPa on 12/27/2022). NOAA's High Tide Flooding Likelihood is low at 1.7%, with a distance to the flood threshold of -0.912 meters, indicating that water levels are expected to remain below critical levels.

Wind speeds are moderate at around 14 mph with a wind direction predominantly from the south-southwest (194 degrees), which does not significantly contribute to flood risk in this region. Compared to the historical Category 3 event on 12/27/2023, where the tide height was 17.460 feet and barometric pressure was 1006.1 hPa, today's higher pressure and similar tide height suggest a low risk of significant flooding.

Considering these factors, the flood potential is categorized as Category 3, indicating conditions close to a flood event and worth monitoring, but unlikely to cause flood damage.

Day 2: 2024-11-15

CATEGORY 3

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

WHEN From 15:00 PST to 16:00 PST.

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

ADDITIONAL DETAILS...

On November 15, 2024, the high tide is forecasted for 15:12 PST with an expected tide height similar to Day 1. The barometric pressure at this time is projected to be 1015.16 hPa, slightly lower than the previous day but still considerably higher than during historical severe flooding events. NOAA's Flood Likelihood remains low at 1.6%, with water levels anticipated to stay below the flood threshold by -0.935 meters.

Wind conditions are calm, with speeds around 5 mph and a direction from the northeast (41 degrees), which is not associated with increased flood risk in Redondo Beach. The combination of moderate tide heights and relatively high barometric pressure suggests a low likelihood of significant flooding, similar to the conditions on Day 1.

Based on this analysis, the flood potential remains at Category 3, indicating that conditions are close to a flood event and worth monitoring, but are unlikely to cause flood damage.

Day 3: 2024-11-16

CATEGORY 3

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

WHEN From 15:30 PST to 16:30 PST.

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

ADDITIONAL DETAILS...

On November 16, 2024, a high tide is expected at 15:48 PST with a slightly lower tide height than the previous days. The barometric pressure is forecasted to be 1025.49 hPa, which is higher than the pressures during historical flood events, further reducing the likelihood of severe flooding. NOAA's Flood Likelihood is low at 0.8%, with a significant distance below the flood threshold (-1.076 meters).

Wind speeds are moderate, averaging around 9 mph from the south-southeast (168 degrees), which does not contribute to increased flood risk. Compared to historical events, particularly the Category 4 event on 11/15/2021 with a tide height of 21.506 feet and much lower barometric pressure (<=1002 hPa), the conditions on Day 3 suggest a minimal risk.

Taking these factors into account, the flood potential is categorized as Category 3, indicating conditions close to a flood event and worth monitoring, but unlikely to cause flood damage.

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.
