Flood Watch

Redondo Beach, WA

Day 1: 2024-11-25

CATEGORY 3

WHAT Minor coastal flooding is possible. Slight inundation may occur in low-lying areas near the shoreline.

WHEN From 12:00 PM to 2:00 PM PST on November 25, 2024.

IMPACTS Minimal impacts expected. Flooding is unlikely to cause damage but monitoring conditions is advised.

ADDITIONAL DETAILS...

Step 1: Assess Barometric Pressure

• The barometric pressure is 1018.3 hPa, significantly higher than in historical severe flood events. This indicates less severe weather conditions and a lower likelihood of major flooding.

Step 2: Evaluate Tide Height

• The tide height peaks at approximately 19.118 ft at 12:54 PM, which is higher than the historical Category 3 event but lower than Category 4 and 5 events. This suggests a moderate risk for minor flooding.

Step 3: Consider Wind Direction and Speed

• Wind speeds are low at 2 mph from the NW (316°). This is unlikely to contribute significantly to flooding.

Step 4: Integrate NOAA High Tide Flooding Likelihood

• NOAA's forecast indicates a Low flood likelihood with a 0.0% chance and a significant distance below the flood threshold.

Conclusion:

• Based on the high barometric pressure, moderate tide height, low wind speeds, and NOAA's low flood likelihood, the flood category is predicted to be Category 3. Monitoring conditions is recommended, but significant flooding is not anticipated.

Day 2: 2024-11-26

CATEGORY 3

WHAT Minor coastal flooding is possible. Slight inundation may occur in low-lying areas near the shoreline.

WHEN From 12:00 PM to 2:00 PM PST on November 26, 2024.

IMPACTS Minimal impacts expected. Flooding is unlikely to cause damage but monitoring conditions is advised.

ADDITIONAL DETAILS...

Step 1: Assess Barometric Pressure

• The barometric pressure is 1001.1 hPa, lower than on Day 1 but still above critical historical thresholds. This does not indicate severe weather conditions.

Step 2: Evaluate Tide Height

• The tide height peaks at approximately 19.025 ft at 1:18 PM, similar to Day 1 and below historical severe event levels. This suggests a moderate risk for minor flooding.

Step 3: Consider Wind Direction and Speed

• Wind speeds are low at 2 mph from the N (10°). The wind is not expected to have a significant impact on flooding.

Step 4: Integrate NOAA High Tide Flooding Likelihood

• NOAA's forecast indicates a Low flood likelihood with a 0.0% chance and a significant distance below the flood threshold.

Conclusion:

• Considering the slightly lower barometric pressure, similar tide heights, low wind speeds, and NOAA's low flood likelihood, the flood category remains at Category 3. Monitoring is advised, but significant flooding is not expected.

Day 3: 2024-11-27

CATEGORY 2

WHAT No risk of flooding is expected. Normal conditions near the shoreline.

WHEN N/A

IMPACTS No impacts expected.

ADDITIONAL DETAILS...

Step 1: Assess Barometric Pressure

• The barometric pressure is 1002.6 hPa, which is higher than on Day 2 and does not indicate severe conditions.

Step 2: Evaluate Tide Height

• The tide height peaks at approximately 18.922 ft at 1:42 PM, slightly lower than previous days and well below historical severe event levels.

Step 3: Consider Wind Direction and Speed

• Wind speeds are minimal at 1-2 mph from varying directions. Wind impact on flooding is negligible.

Step 4: Integrate NOAA High Tide Flooding Likelihood

• NOAA's forecast indicates a Low flood likelihood with a 0.0% chance and a significant distance below the flood threshold.

Conclusion:

• With higher barometric pressure, lower tide heights, and minimal wind speeds, the flood category is determined to be Category 2. No flooding is expected.

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.
