HEADING: Flood Watch

Redondo Beach, WA

Day 1: 2024-12-18

CATEGORY 3

WHAT: Minor coastal flooding possible. Close to a flood event and worth monitoring, but unlikely to cause flood damage.

WHEN: From 7:30 AM to 8:30 AM PST and from 5:30 PM to 6:30 PM PST.

IMPACTS: Minor flooding of low-lying areas and shorelines may occur. Isolated road closures are unlikely.

ADDITIONAL DETAILS...

Barometric Pressure: The barometric pressure during high tide is 1034.51 hPa, which is significantly higher than in historical severe flood events. High pressure suggests stable atmospheric conditions and reduces the likelihood of significant coastal flooding.

Tide Height: The maximum tide height is 20.586 feet, comparable to the historical Category 4 event on 12/18/2024. However, without the accompanying low barometric pressure, the risk is moderated.

Wind Direction and Speed: Winds are from the south-southwest at 11 kmph (7 mph). This is less intense than in past higher-category events, indicating a lower impact on potential flooding.

NOAA High Tide Flooding Likelihood: NOAA forecasts a high flood likelihood with a score of 10.0%. Despite this, the high barometric pressure and moderate wind conditions reduce the overall flood risk.

Based on these factors, the flood potential for Day 1 is categorized as Category 3, indicating conditions are close to a flood event and worth monitoring, but significant flood damage is unlikely.


Day 2: 2024-12-19

CATEGORY 2

WHAT: No risk of flooding expected.

WHEN: Not applicable.

IMPACTS: No significant impacts anticipated.

ADDITIONAL DETAILS...

Barometric Pressure: The pressure remains high at 1028.68 hPa during peak tides, suggesting continued stable weather conditions.

Tide Height: The maximum tide height decreases to 20.205 feet, lower than Day 1 and below levels associated with flooding in historical data.

Wind Direction and Speed: Winds are light, with no significant contribution to flooding risk.

NOAA High Tide Flooding Likelihood: NOAA indicates a low flood likelihood with a score of 3.5%, reflecting minimal risk.

Considering these factors, the flood potential for Day 2 is categorized as Category 2, representing no risk of flooding.


Day 3: 2024-12-20

CATEGORY 2

WHAT: No risk of flooding expected.

WHEN: Not applicable.

IMPACTS: No significant impacts anticipated.

ADDITIONAL DETAILS...

Barometric Pressure: Barometric pressure during high tide is 1026.83 hPa, maintaining the trend of high pressure and stable conditions.

Tide Height: The maximum tide height further decreases to 20.090 feet, indicating even lower flood potential.

Wind Direction and Speed: Winds remain light and variable, unlikely to influence flooding risk.

NOAA High Tide Flooding Likelihood: NOAA's flood likelihood is low at 1.4%, supporting the assessment of minimal flood risk.

Based on the analysis, the flood potential for Day 3 is categorized as Category 2, indicating no risk of flooding.
