Flood Watch

Redondo Beach, WA

Day 1: 2024-08-17

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 01:00 AM to 04:00 PM PST.

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

ADDITIONAL DETAILS...

On August 17, the high tide at 01:18 AM is expected to reach a height of approximately 17.723 feet with a barometric pressure of 1010.22 hPa. The second high tide at 16:36 PM will reach around 19.015 feet with a barometric pressure of 1011.25 hPa. These conditions are similar to the Category 3 event on 12/27/2023 but with slightly higher pressure, reducing the flood risk. Wind speeds are relatively low, and NOAA's flood likelihood is low at 0.0%.

Day 2: 2024-08-18

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 05:00 PM 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 1011.64 hPa. The second high tide at 17:00 PM will reach around 19.320 feet with a barometric pressure of 1013.31 hPa. These conditions are similar to the Category 3 event on 12/27/2023 but with slightly higher pressure, reducing the flood risk. Wind speeds are relatively low, and NOAA's flood likelihood is low at 0.0%.

Day 3: 2024-08-19

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 06:00 PM 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 1016.62 hPa. The second high tide at 17:24 PM will reach around 19.596 feet with a barometric pressure of 1015.70 hPa. These conditions are similar to the Category 3 event on 12/27/2023 but with significantly higher pressure, reducing the flood risk further. Wind speeds are relatively low, and NOAA's flood likelihood is low at 0.0%.

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 for each day:

Day 1 (2024-08-17):

  1. Barometric Pressure:
  2. High tide at 01:18 AM: Pressure = 1010.22 hPa
  3. High tide at 16:36 PM: Pressure = 1011.25 hPa
  4. Both pressures are higher than the critical threshold (992.8 hPa), indicating lower flood risk.

  5. Tide Height:

  6. High tide heights are significant but not extreme compared to historical severe events.

  7. Wind Direction and Speed:

  8. Wind speeds are relatively low (around 10 mph) and not from critical directions that exacerbate flooding.

  9. NOAA High Tide Flooding Likelihood:

  10. Likelihood is 0%, indicating very low risk.

Day 2 (2024-08-18):

  1. Barometric Pressure:
  2. High tide at 02:18 AM: Pressure = 1011.64 hPa
  3. High tide at 17:00 PM: Pressure = 1013.31 hPa
  4. Both pressures are higher than the critical threshold (992.8 hPa), indicating lower flood risk.

  5. Tide Height:

  6. High tide heights are significant but not extreme compared to historical severe events.

  7. Wind Direction and Speed:

  8. Wind speeds are relatively low (around 10 mph) and not from critical directions that exacerbate flooding.

  9. NOAA High Tide Flooding Likelihood:

  10. Likelihood is 0%, indicating very low risk.

Day 3 (2024-08-19):

  1. Barometric Pressure:
  2. High tide at 03:12 AM: Pressure = 1016.62 hPa
  3. High tide at 17:24 PM: Pressure = 1015.70 hPa
  4. Both pressures are significantly higher than the critical threshold (992.8 hPa), indicating very low flood risk.

  5. Tide Height:

  6. High tide heights are significant but not extreme compared to historical severe events.

  7. Wind Direction and Speed:

  8. Wind speeds are relatively low (around 10 mph) and not from critical directions that exacerbate flooding.

  9. NOAA High Tide Flooding Likelihood:

  10. Likelihood is 0%, indicating very low risk.

Based on this analysis, all three days fall into Category 2 for minor coastal flooding potential due to higher barometric pressures and moderate tide heights without significant wind impact or NOAA flood likelihood indicators suggesting otherwise.
