Flood Watch

Redondo Beach, WA

Day 1: 2024-11-16

CATEGORY 2

WHAT No risk of flooding expected. Normal tidal conditions are anticipated.

WHEN High tides at approximately 5:36 AM and 3:48 PM PST.

IMPACTS No significant impacts expected. Coastal areas should experience typical tidal conditions.

ADDITIONAL DETAILS...

On Day 1, the peak tide height reaches around 20.157 feet at 5:36 AM. The barometric pressure is high, with a mean pressure of 1022.53 hPa during the morning high tide and 1025.08 hPa during the afternoon high tide. Wind speeds are low, ranging from 5 to 6 km/h (3 to 4 mph), with wind directions predominantly from the SSE (approximate wind direction degrees between 159 and 169). NOAA's Flood Likelihood is low at 0.8%, with a significant distance to the flood threshold (-1.08m). Compared to historical events, these conditions indicate a very low risk of flooding, justifying a Category 2 classification.

Day 2: 2024-11-17

CATEGORY 2

WHAT No risk of flooding expected. Normal tidal conditions are anticipated.

WHEN High tides at approximately 6:30 AM and 4:30 PM PST.

IMPACTS No significant impacts expected. Coastal areas should experience typical tidal conditions.

ADDITIONAL DETAILS...

On Day 2, the maximum tide height is approximately 20.538 feet at 6:30 AM. The barometric pressure remains high, with mean pressures of 1028.68 hPa during the morning high tide and 1037.66 hPa during the afternoon high tide. Wind speeds are moderate, with gusts up to 22 km/h (14 mph) and wind directions from the SSW (wind direction degrees ranging from 190 to 217). NOAA's Flood Likelihood is low at 3.4%, with a distance to the flood threshold of -0.77m. These conditions, when compared to historical data, suggest a minimal risk of flooding, consistent with a Category 2 rating.

Day 3: 2024-11-18

CATEGORY 3

WHAT Conditions are close to a flood event and worth monitoring, but significant flooding is unlikely.

WHEN High tide at approximately 7:24 AM PST.

IMPACTS Minor coastal flooding of low-lying areas is possible. Elevated water levels near shorelines may occur.

ADDITIONAL DETAILS...

On Day 3, the peak tide height reaches about 20.544 feet at 7:24 AM, slightly higher than the previous two days but still below the 21-foot threshold associated with higher flood risks in historical events. The barometric pressure is high at 1033.20 hPa during the high tide, which generally indicates stable weather conditions and reduces the likelihood of severe flooding. Wind speeds are moderate, with maximum gusts around 18 km/h (11 mph), and wind directions from the S to SSW (wind direction degrees between 186 and 203).

NOAA's Flood Likelihood for this day is noted as 'High' with a likelihood percent of 5.2% and a distance to the flood threshold of -0.68m, indicating that the water levels are closer to the threshold than on previous days. While this suggests an increased potential for minor flooding compared to Days 1 and 2, the high barometric pressure and absence of significant wind anomalies lessen the overall risk. When compared to the historical Category 3 event on 12/27/2023, which had lower barometric pressure and a lower tide height, the current conditions are similar but with a higher barometric pressure. Therefore, Day 3 is classified as Category 3, warranting monitoring but not indicating a significant or dangerous flood risk.

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.
