Flood Watch

Redondo Beach, WA

Day 1: 2024-09-15

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 01:00 AM to 03:00 AM PST.

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

ADDITIONAL DETAILS...

On 2024-09-15, the high tide at 01:18 AM is expected to reach a height of approximately 17.310 feet with a barometric pressure of 1009.38 hPa. This pressure is higher than the critical threshold of 992.8 hPa, reducing the likelihood of significant flooding. The wind speed is relatively low at around 2 mph from the SE direction, which does not significantly contribute to flood risk. Historical data indicates that similar conditions have resulted in minor flooding events.

Day 2: 2024-09-16

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 02:00 AM to 04:00 AM PST.

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

ADDITIONAL DETAILS...

On 2024-09-16, the high tide at 02:18 AM is expected to reach a height of approximately 17.909 feet with a barometric pressure of 1007.60 hPa. This pressure is higher than the critical threshold of 992.8 hPa, reducing the likelihood of significant flooding. The wind speed is relatively low at around 3 mph from the NNE direction, which does not significantly contribute to flood risk. Historical data indicates that similar conditions have resulted in minor flooding events.

Day 3: 2024-09-17

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 03:00 AM to 05:00 AM PST.

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

ADDITIONAL DETAILS...

On 2024-09-17, the high tide at 03:18 AM is expected to reach a height of approximately 18.446 feet with a barometric pressure of 1016.87 hPa. This pressure is significantly higher than the critical threshold of 992.8 hPa, reducing the likelihood of significant flooding. The wind speed is relatively low at around 5 mph from the S direction, which does not significantly contribute to flood risk. Historical data indicates that similar conditions have resulted in minor 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.


Analysis Summary:

Based on the provided data for Redondo Beach, WA over the next three days (2024-09-15 to 2024-09-17), the flood potential has been categorized as Category 2 for each day. This categorization is based on:

  1. Barometric Pressure: All days show pressures well above the critical threshold (992.8 hPa), indicating lower risk.
  2. Tide Heights: While tides are high (ranging from ~17 to ~18 feet), they are not extreme compared to historical severe flood events.
  3. Wind Speed and Direction: Wind speeds are relatively low (ranging from ~2 to ~5 mph) and directions do not significantly exacerbate flood risks.
  4. NOAA Flood Likelihood: NOAA's analysis indicates a low likelihood of flooding for these dates.

Overall, while minor coastal flooding may occur, significant property damage or severe flooding is unlikely based on current data and historical comparisons.
