Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding possible. Close to a flood event and worth monitoring, but unlikely to cause flood damage.
WHEN From 10:30 AM to 12:30 PM PST on November 23, 2024.
IMPACTS Minor flooding of very low-lying areas along the coast. Little to no property damage expected.
Step 1: Assess Barometric Pressure
The barometric pressure is significantly high at 1026.91 hPa during the high tide at 11:42 AM, compared to pressures during historical flood events (at or below 1002 hPa). This high pressure indicates less severe weather conditions and a reduced likelihood of flooding.
Step 2: Evaluate Tide Height
The tide height is forecasted to reach 19.010 ft, which is higher than the Category 3 historical event (17.460 ft) but lower than Category 4 and 5 events (over 21 ft). This suggests a moderate risk that is worth monitoring.
Step 3: Consider Wind Direction and Speed
Wind direction is from the south at around 188 degrees with wind speeds approximately 11 kmph (7 mph). These moderate wind conditions are not expected to significantly impact the flooding risk.
Step 4: Integrate NOAA High Tide Flooding Likelihood
NOAA's forecast indicates a low flood likelihood with a 0.0% chance and a distance of -1.85m below the flood threshold. This supports the assessment of a lower risk of significant flooding.
Step 5: Synthesize Information and Forecast Flood Category
Combining the high barometric pressure, moderate tide height, and low NOAA flood likelihood, the flood risk is assessed as Category 3. Monitoring is advised, but significant flooding is unlikely under the current conditions.
CATEGORY 3
WHAT Minor coastal flooding possible. Close to a flood event and worth monitoring, but unlikely to cause flood damage.
WHEN From 11:30 AM to 1:30 PM PST on November 24, 2024.
IMPACTS Minor flooding of very low-lying areas along the coast. Little to no property damage expected.
Step 1: Assess Barometric Pressure
The barometric pressure is around 1011 hPa during the peak tide at noon, which is higher than pressures observed during historical flooding events. This indicates stable atmospheric conditions and a lower risk of severe weather-related flooding.
Step 2: Evaluate Tide Height
The expected tide height is 19.175 ft at its peak, slightly higher than the Category 3 historical event but below the critical threshold associated with significant flooding (over 21 ft).
Step 3: Consider Wind Direction and Speed
Winds are light, predominantly from the south to southeast at speeds between 3 to 5 kmph (2 to 3 mph). These gentle winds are unlikely to contribute to increased flood risk.
Step 4: Integrate NOAA High Tide Flooding Likelihood
NOAA's forecast indicates a low flood likelihood with a 0.0% chance and a distance of -1.98m below the flood threshold. This data suggests minimal risk of flooding.
Step 5: Synthesize Information and Forecast Flood Category
Considering the relatively high barometric pressure, moderate tide heights, and low NOAA flood likelihood, the flood category remains at Category 3. Monitoring is recommended, but significant flooding is not expected.

WHAT Minor coastal flooding possible. Close to a flood event and worth monitoring, but unlikely to cause flood damage.
WHEN From 12:00 PM to 2:00 PM PST on November 25, 2024.
IMPACTS Minor flooding of very low-lying areas along the coast. Little to no property damage expected.
Step 1: Assess Barometric Pressure
The barometric pressure is approximately 1020.34 hPa during the high tide at 12:54 PM, which is substantially higher than pressures recorded during significant historical flood events. This suggests a stable weather pattern with low risk of severe flooding.
Step 2: Evaluate Tide Height
The maximum tide height is forecasted to be around 19.118 ft, consistent with the previous days and below the levels seen in historical Category 4 and 5 events.
Step 3: Consider Wind Direction and Speed
Winds are light to moderate, shifting from northeast to northwest with speeds ranging from 4 to 8 kmph (2 to 5 mph). These wind conditions are not expected to significantly impact the risk of flooding.
Step 4: Integrate NOAA High Tide Flooding Likelihood
NOAA's forecast continues to show a low flood likelihood with a 0.0% chance and a distance of -2.05m below the flood threshold. This indicates a minimal risk of high tide flooding.
Step 5: Synthesize Information and Forecast Flood Category
Taking into account the high barometric pressure, moderate tide heights, and low NOAA flood likelihood, the flood risk is assessed as Category 3. Continued monitoring is advised, but significant flooding is unlikely.
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.
