Flood Watch

Redondo Beach, WA

Day 1: 2024-08-21

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 05:00 AM to 07:00 AM PST.

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

ADDITIONAL DETAILS...

The barometric pressure is relatively high at 1007.06 hPa during the high tide at 05:06 AM, which reduces the likelihood of severe flooding. The tide height is significant but not extreme, peaking at around 18.674 feet at 05:06 AM. Wind speeds are moderate, and the wind direction is from the SSE, which does not significantly exacerbate flooding conditions. Historical data indicates that similar conditions have not led to severe flooding events.

Day 2: 2024-08-22

CATEGORY 3

WHAT Moderate coastal flooding expected. Possible inundation of up to 1.0 feet above ground level near shorelines and low-lying areas.

WHEN From 06:00 AM to 08:00 AM PST.

IMPACTS Moderate flooding of low-lying areas, parks, and roads. Some road closures possible.

ADDITIONAL DETAILS...

The barometric pressure is lower at 1002.20 hPa during the high tide at 06:06 AM, which increases the likelihood of moderate flooding. The tide height is significant, peaking at around 18.437 feet at 06:06 AM. Wind speeds are moderate, and the wind direction is from the NNE, which could push more seawater towards the coast. Historical data indicates that similar conditions have led to moderate flooding events.

Day 3: 2024-08-23

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 07:00 AM to 09:00 AM PST.

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

ADDITIONAL DETAILS...

The barometric pressure is relatively high at 1006.43 hPa during the high tide at 07:06 AM, which reduces the likelihood of severe flooding. The tide height is significant but not extreme, peaking at around 18.052 feet at 07:06 AM. Wind speeds are moderate, and the wind direction is from the SSW, which does not significantly exacerbate flooding conditions. Historical data indicates that similar conditions have not led to severe flooding events.

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 (2024-08-21):

  1. Barometric Pressure: The pressure is relatively high at both high tides (1007.06 hPa and 1004.75 hPa), reducing the likelihood of severe weather conditions.
  2. Tide Height: The highest tide reaches around 18.674 feet, which is significant but not extreme.
  3. Wind Direction: Winds are from the SSE and SE with moderate speeds (5-9 kmph), which do not significantly exacerbate flooding.
  4. NOAA Likelihood: NOAA's flood likelihood for this date is low (0%), further supporting a lower flood risk assessment.
  5. Historical Comparison: Similar conditions in historical data have not led to severe flooding events.

Day 2 (2024-08-22):

  1. Barometric Pressure: The pressure drops to around 1002.20 hPa during one of the high tides, increasing flood risk.
  2. Tide Height: The highest tide reaches around 18.437 feet.
  3. Wind Direction: Winds are from the NNE with moderate speeds (3-10 kmph), potentially pushing more seawater towards the coast.
  4. NOAA Likelihood: NOAA's flood likelihood for this date remains low (0%), but historical data suggests a moderate risk under these conditions.
  5. Historical Comparison: Similar conditions in historical data have led to moderate flooding events.

Day 3 (2024-08-23):

  1. Barometric Pressure: The pressure remains relatively high at both high tides (1006.43 hPa), reducing severe weather likelihood.
  2. Tide Height: The highest tide reaches around 18.052 feet.
  3. Wind Direction: Winds are from the SSW with moderate speeds (5-14 kmph), which do not significantly exacerbate flooding.
  4. NOAA Likelihood: NOAA's flood likelihood for this date is low (0%), further supporting a lower flood risk assessment.
  5. Historical Comparison: Similar conditions in historical data have not led to severe flooding events.

This analysis integrates weather observations, tide data, barometric pressure readings, and historical event comparisons to provide a comprehensive flood risk assessment for Redondo Beach, WA over the next three days.
