Redondo Beach, WA
CATEGORY 3
WHAT: Minor coastal flooding possible. A high tide of up to 18.78 feet is expected, combined with moderate barometric pressure and low wind speeds.
WHEN: From 3:00 PM to 4:00 PM PST on 2024-10-30.
IMPACTS: Minor flooding of low-lying areas, parks, and roads near the shoreline. Unlikely to cause significant property damage, but caution is advised for activities close to the water.
Barometric Pressure: The pressure is 1018.13 hPa during the peak tide, which is higher than pressures observed in historical severe flood events (e.g., 1006.1 hPa in the Category 3 event of 12/27/2023). This suggests stable atmospheric conditions.
Tide Height: The expected tide height is 18.78 feet, higher than the historical Category 3 event but below Category 4 levels. This indicates a moderate potential for minor flooding.
Wind Direction and Speed: Winds are from the southwest at approximately 3 mph. This is similar to winds observed in past Category 3 events and is not likely to significantly impact flood potential.
NOAA High Tide Flooding Likelihood: NOAA indicates a low flood likelihood with 0.0% probability and a distance of -2.4 meters below the flood threshold, supporting a lower risk assessment.
Synthesis: Considering the moderate tide height and high barometric pressure, the flood potential is categorized as Category 3—close to a flood event and worth monitoring but unlikely to cause significant flood damage.
CATEGORY 3
WHAT: Minor coastal flooding possible. A high tide of up to 18.70 feet is expected, with high barometric pressure and moderate wind speeds.
WHEN: From 3:00 PM to 4:00 PM PST on 2024-10-31.
IMPACTS: Potential minor flooding in low-lying coastal areas, including parks and walking paths. Property damage is unlikely, but caution is recommended for waterfront activities.
Barometric Pressure: The pressure is 1020.84 hPa during the high tide, higher than in previous flooding events, indicating stable weather conditions.
Tide Height: The tide height is expected to reach 18.70 feet, similar to Day 1 and above the historical Category 3 event level.
Wind Direction and Speed: Winds are from the north at approximately 9 mph. This is slightly higher than Day 1 but still moderate and not expected to contribute significantly to flood risk.
NOAA High Tide Flooding Likelihood: NOAA reports a low flood likelihood with 0.0% probability and a distance of -2.59 meters below the flood threshold.
Synthesis: Given the high barometric pressure, moderate tide height, and NOAA's low flood likelihood, the flood potential remains at Category 3, warranting monitoring but not expected to cause significant damage.
CATEGORY 2
WHAT: No significant risk of coastal flooding expected. Tides are normal, and weather conditions are stable.
WHEN: Normal tidal cycles throughout the day on 2024-11-01.
IMPACTS: No flooding anticipated. Coastal areas are expected to remain unaffected.
Barometric Pressure: Very high pressure at 1025.04 hPa during peak tides, indicating very stable atmospheric conditions.
Tide Height: Expected maximum tide height is approximately 18.16 feet, lower than the previous two days and well below levels associated with flooding events.
Wind Direction and Speed: Winds are light, ranging from 2 to 3 mph from the south-southwest, unlikely to influence tidal effects.
NOAA High Tide Flooding Likelihood: NOAA indicates a low flood likelihood with 0.0% probability and a distance of -2.61 meters below the flood threshold.
Synthesis: The combination of very high barometric pressure, lower tide heights, and minimal wind effects results in a Category 2 assessment, indicating no substantial flood risk.
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.
