Flood Watch

Redondo Beach, WA

Day 1: 2024-08-18

CATEGORY 2

WHAT Minor coastal flooding expected. Possible inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.

*WHEN From 02:00 AM to 06:00 AM PST.

IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.

ADDITIONAL DETAILS...

On August 18, the high tide at 02:18 AM is expected to reach a height of approximately 18.137 feet with a barometric pressure of 1009.68 hPa. This pressure is higher than the critical threshold of 992.8 hPa, reducing the likelihood of severe flooding. The wind direction is from the south at a moderate speed, which does not significantly exacerbate flooding conditions. NOAA's flood likelihood analysis for this date indicates a low likelihood of flooding with a distance to the threshold of -1.84m.

Day 2: 2024-08-19

CATEGORY 2

WHAT Minor coastal flooding expected. Possible inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.

WHEN From 03:00 AM to 06:00 AM PST.

IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.

ADDITIONAL DETAILS...

On August 19, the high tide at 03:12 AM is expected to reach a height of approximately 18.504 feet with a barometric pressure of 1016.66 hPa. This pressure is significantly higher than the critical threshold, indicating stable weather conditions and reducing the risk of severe flooding. The wind direction remains moderate and does not pose additional risks. NOAA's flood likelihood analysis for this date also indicates a low likelihood of flooding with a distance to the threshold of -1.66m.

Day 3: 2024-08-20

CATEGORY 2

WHAT Minor coastal flooding expected. Possible inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.

WHEN From 04:00 AM to 07:00 AM PST.

IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.

ADDITIONAL DETAILS...

On August 20, the high tide at 04:06 AM is expected to reach a height of approximately 18.703 feet with a barometric pressure of 1017.14 hPa. This pressure remains well above the critical threshold, suggesting minimal risk for severe weather conditions that could lead to significant flooding. Wind conditions are stable and do not contribute to increased flood risk. NOAA's flood likelihood analysis for this date indicates a low likelihood of flooding with a distance to the threshold of -1.31m.

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.


Forecast Reasoning:

Step-by-step analysis was conducted for each day based on provided data:

  1. Barometric Pressure: All days show pressures well above the critical threshold (992.8 hPa), indicating stable weather conditions.
  2. Tide Height: High tides are significant but not extreme compared to historical severe events.
  3. Wind Direction: Moderate wind speeds from non-critical directions.
  4. NOAA Flood Likelihood: All days show low likelihood percentages with significant distances from flood thresholds.

Based on these factors, all three days are categorized as Category 2 events, indicating minor coastal flooding with minimal impact on property and infrastructure.
