Flood Watch

Redondo Beach, WA

Day 1: 2024-09-09

CATEGORY 2

WHAT Minor coastal flooding expected. Possible inundation of up to 1 foot above ground level near shorelines and low-lying areas.

*WHEN From 07:00 PM to 09:00 PM PST.

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

ADDITIONAL DETAILS...

The high tide at 2024-09-09 19:48 is expected to reach 17.635 feet with a barometric pressure of 1009.27 hPa. This pressure is higher than the critical threshold of 992.8 hPa, reducing the likelihood of severe flooding. Wind speeds are relatively low at around 4 mph from the SSE direction, which is not expected to significantly exacerbate flooding conditions. Historical data indicates that similar conditions have resulted in minor flooding events.

Day 2: 2024-09-10

CATEGORY 1

WHAT No significant coastal flooding expected.

WHEN No specific high-risk period identified.

IMPACTS No significant impacts anticipated.

ADDITIONAL DETAILS...

The high tide at 2024-09-10 04:48 is expected to reach 11.497 feet with a barometric pressure of 1010.52 hPa. This pressure is well above the critical threshold, indicating stable weather conditions. Wind speeds are low, and the wind direction is not aligned with historical flood-inducing patterns. The NOAA flood likelihood for this date is also low, further supporting the assessment of minimal flood risk.

Day 3: 2024-09-11

CATEGORY 1

WHAT No significant coastal flooding expected.

WHEN No specific high-risk period identified.

IMPACTS No significant impacts anticipated.

ADDITIONAL DETAILS...

The high tide at 2024-09-11 12:12 is expected to reach 17.300 feet with a barometric pressure of 1014.21 hPa. This pressure is significantly higher than the critical threshold, indicating very stable weather conditions. Wind speeds are low, and the wind direction does not suggest any potential for exacerbating flood conditions. The NOAA flood likelihood for this date is also low, confirming minimal 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.

Forecast Reasoning:

Day 1 (2024-09-09):

  1. Assess Barometric Pressure: The barometric pressure is at 1009.27 hPa, which is higher than the critical threshold of 992.8 hPa.
  2. Evaluate Tide Height: The tide height reaches up to 17.635 feet, which is significant but not extreme.
  3. Consider Wind Direction: Wind direction from SSE at around 4 mph does not align with historical severe flood events.
  4. Integrate NOAA High Tide Flooding Likelihood: NOAA's forecast indicates a low likelihood of flooding.
  5. Synthesize Information: Given the higher barometric pressure and moderate tide height, the flood category for this day is predicted to be Category 2.

Day 2 (2024-09-10):

  1. Assess Barometric Pressure: The barometric pressure is at 1010.52 hPa, indicating stable weather conditions.
  2. Evaluate Tide Height: The tide height reaches up to 11.497 feet, which is not significant enough to cause concern.
  3. Consider Wind Direction: Wind speeds are low and do not suggest any potential for exacerbating flood conditions.
  4. Integrate NOAA High Tide Flooding Likelihood: NOAA's forecast indicates a very low likelihood of flooding.
  5. Synthesize Information: Given the high barometric pressure and low tide height, the flood category for this day is predicted to be Category 1.

Day 3 (2024-09-11):

  1. Assess Barometric Pressure: The barometric pressure is at 1014.21 hPa, indicating very stable weather conditions.
  2. Evaluate Tide Height: The tide height reaches up to 17.300 feet, which is significant but not extreme.
  3. Consider Wind Direction: Wind speeds are low and do not suggest any potential for exacerbating flood conditions.
  4. Integrate NOAA High Tide Flooding Likelihood: NOAA's forecast indicates a very low likelihood of flooding.
  5. Synthesize Information: Given the very high barometric pressure and moderate tide height, the flood category for this day is predicted to be Category 1.

This analysis provides a clear understanding of potential flood risks based on current data and historical comparisons, ensuring users are well-informed about possible coastal flooding in Redondo Beach, WA over the next three days.
