HEADING: Flood Watch

Redondo Beach, WA

DayInfo1: Day 1: 2024-10-12

CATEGORY 3

WHAT Minor coastal flooding is possible. Elevated tide levels may lead to minor inundation in low-lying areas near the shore.

WHEN From 12:00 PM to 2:00 PM PST.

IMPACTS Minor flooding of low-lying areas, parks, and roads adjacent to the coastline. Significant property damage is not expected, but caution is advised.

ADDITIONAL DETAILS...

• Barometric Pressure: The pressure is high at 1020.55 hPa during the peak tide at 1:30 PM. This is significantly higher than pressures observed during historical flood events, suggesting stable atmospheric conditions.
• Tide Height: The peak tide is at 18.666 ft, which is higher than the previous Category 3 event (17.460 ft) but lower than Category 4 events. This elevated tide height warrants monitoring.
• Wind Direction and Speed: Winds are from the NW during high tide with low speeds around 3 mph. While the wind direction can contribute to coastal flooding, the low wind speed minimizes this risk.
• NOAA Flood Likelihood: NOAA indicates a low likelihood of flooding with a 0.0% chance and a distance to threshold of -2.56 m, suggesting tides are well below flood trigger levels.

Overall, while the tide heights are elevated, the high barometric pressure and low wind speeds reduce the risk of significant flooding. Conditions are close to a flood event but are unlikely to cause damage.

DayInfo2: Day 2: 2024-10-13

CATEGORY 3

WHAT Minor coastal flooding is possible due to higher tide levels compared to Day 1.

WHEN From 12:00 PM to 2:00 PM PST.

IMPACTS Possible minor flooding of low-lying coastal areas and roads. Significant property damage is not anticipated, but stay informed on local conditions.

ADDITIONAL DETAILS...

• Barometric Pressure: The pressure drops to 1008.16 hPa during the peak tide at 2:06 PM. This is lower than Day 1 but still higher than pressures during historical severe flood events.
• Tide Height: The peak tide reaches 19.021 ft, slightly higher than Day 1 and approaching levels seen in past Category 4 events.
• Wind Direction and Speed: Winds are from the south (S to SSW) at low speeds between 3-5 mph. This wind direction is less likely to contribute to coastal flooding in this area.
• NOAA Flood Likelihood: NOAA reports a low likelihood of flooding with a 0.0% chance and a distance to threshold of -2.14 m.

Despite the higher tide and lower barometric pressure, the conditions do not meet the thresholds observed in historical Category 4 events. Minor flooding is possible, and conditions should be monitored.

DayInfo3: Day 3: 2024-10-14

CATEGORY 4

WHAT Moderate coastal flooding is likely due to elevated tide levels and lower barometric pressure.

WHEN From 12:00 PM to 3:00 PM PST.

IMPACTS Flooding of low-lying areas near the shoreline is expected. Minor property damage is possible. Be prepared for potential road closures and disruptions.

ADDITIONAL DETAILS...

• Barometric Pressure: Pressure decreases significantly to 999.86 hPa during the peak tide at 2:36 PM, similar to pressures observed during historical Category 4 events.
• Tide Height: The peak tide reaches 19.384 ft, comparable to historical Category 4 events (e.g., 19.255 ft on 01/07/2022).
• Wind Direction and Speed: Winds are from the SSE at moderate speeds of about 6 mph. While not from the W/NW, they should still be monitored as part of the overall conditions.
• NOAA Flood Likelihood: NOAA continues to indicate a low likelihood of flooding with a 0.0% chance, but the distance to threshold decreases to -1.86 m, closer than previous days.

The combination of lower barometric pressure and higher tide levels aligns with historical Category 4 events, indicating that moderate flooding is likely. Residents should stay informed and prepared.

PA: 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.
