Flood Watch

Redondo Beach, WA

Day 1: 2024-10-09

CATEGORY 2

WHAT No flooding expected. Tidal and weather conditions are within normal ranges with no anticipated flood threats.

WHEN Throughout the day on October 9, 2024.

IMPACTS No flooding impacts anticipated for this day.

ADDITIONAL DETAILS...

• Barometric Pressure: High tides on this day occur with pressures of 1003.19 hPa at 12:18 AM and 1008.71 hPa at 7:12 PM. These pressures are significantly higher than those recorded during historical flood events (e.g., pressures below 992.8 hPa in Category 4 and 5 events), indicating stable atmospheric conditions.
• Tide Heights: The maximum predicted tide height is approximately 18.15 ft around 10:00 AM. While this is higher than the tide height during the historical Category 3 event (17.46 ft), the accompanying higher barometric pressure reduces the flood risk.
• Wind Direction and Speed: Winds are light, predominantly from the east and southeast with speeds around 2-4 mph. These wind conditions do not align with those that have historically contributed to flooding (e.g., strong winds from the W/NW).
• NOAA Flood Likelihood: NOAA indicates a low flood likelihood with 0% chance, and a significant distance below the flood threshold (-3.02m).

Comparing these conditions with historical data, the lack of low barometric pressure paired with the tide height suggests no risk of flooding on this day.

Day 2: 2024-10-10

CATEGORY 1

WHAT No flooding expected. Both tidal levels and weather conditions indicate a minimal risk of flooding.

WHEN Throughout the day on October 10, 2024.

IMPACTS No flooding impacts anticipated for this day.

ADDITIONAL DETAILS...

• Barometric Pressure: High tides occur at pressures of 1008.78 hPa at 11:30 AM and 1008.94 hPa at 8:24 PM. These pressures are well above the thresholds associated with historical flooding events, indicating stable weather conditions.
• Tide Heights: The maximum tide height is around 18.15 ft, similar to Day 1. Without the presence of low barometric pressure, this tide height does not pose a flooding risk.
• Wind Direction and Speed: Winds are light, coming from the north and northeast with speeds ranging from 1-7 mph. These conditions are not conducive to flooding.
• NOAA Flood Likelihood: NOAA reports a low flood likelihood with 0% chance, and the distance to the flood threshold remains significant (-3.06m).

All indicators suggest a negligible risk of flooding, and conditions are consistent with those typically classified as Category 1.

Day 3: 2024-10-11

CATEGORY 1

WHAT No flooding expected. Weather and tidal conditions remain stable with no anticipated flood threats.

WHEN Throughout the day on October 11, 2024.

IMPACTS No flooding impacts anticipated for this day.

ADDITIONAL DETAILS...

• Barometric Pressure: High tides coincide with a pressure of 1013.09 hPa at both 12:42 PM and 10:24 PM, which is significantly higher than pressures during past flooding events. This high pressure indicates very stable atmospheric conditions.
• Tide Heights: The maximum tide height is slightly lower than previous days and does not reach the levels associated with historical flood events.
• Wind Direction and Speed: Winds are light and variable, predominantly from the north and northeast, with speeds around 2-7 mph. There are no strong winds from the W/NW that could enhance flooding risk.
• NOAA Flood Likelihood: NOAA continues to indicate a low flood likelihood with 0% chance, and the distance to the flood threshold is ample (-2.83m).

Given these conditions, there is no anticipated flood risk for this day, aligning with a Category 1 classification.

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.
