Flood Watch

Redondo Beach, WA

Day 1: 2024-08-22

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 06:00 AM to 07:00 PM PST.

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

ADDITIONAL DETAILS...

The high tide at 06:06 AM on 2024-08-22 is expected to reach a height of approximately 18.44 feet with a barometric pressure of 1000.09 hPa. This pressure is higher than the critical threshold of 992.8 hPa, reducing the likelihood of significant flooding. The wind direction is from the NW at 11 kmph (7 mph), which is not expected to exacerbate flooding conditions significantly. The NOAA flood likelihood for this date is low, with a likelihood percent of 0.0% and a distance to threshold of -0.99m.

Day 2: 2024-08-23

CATEGORY 3

WHAT Moderate coastal flooding possible. Inundation of up to 1 foot above ground level near shorelines and low-lying areas.

WHEN From 07:00 AM to 08:00 PM PST.

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

ADDITIONAL DETAILS...

The high tide at 07:06 AM on 2024-08-23 is expected to reach a height of approximately 18.06 feet with a barometric pressure of 1006.88 hPa. This pressure is higher than the critical threshold but lower than the previous day, indicating a slightly increased risk of flooding. The wind direction is from the S at 9 kmph (6 mph), which may contribute to higher water levels along the coast. The NOAA flood likelihood for this date remains low, with a likelihood percent of 0.0% and a distance to threshold of -1.19m.

Day 3: 2024-08-24

CATEGORY 3

WHAT Moderate coastal flooding possible. Inundation of up to 1 foot above ground level near shorelines and low-lying areas.

WHEN From 08:00 AM to 09:00 PM PST.

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

ADDITIONAL DETAILS...

The high tide at 08:18 AM on 2024-08-24 is expected to reach a height of approximately 17.64 feet with a barometric pressure of 1006.78 hPa. This pressure is higher than the critical threshold but similar to the previous day, indicating a consistent risk level for moderate flooding. The wind direction is from the SSW at 16 kmph (10 mph), which may contribute to higher water levels along the coast. The NOAA flood likelihood for this date remains low, with a likelihood percent of 0.0% and a distance to threshold of -1.36m.

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 based on provided data:

  1. Assess Barometric Pressure:
  2. Day 1: Pressure = 1000.09 hPa (higher than critical threshold)
  3. Day 2: Pressure = 1006.88 hPa (higher than critical threshold)
  4. Day 3: Pressure = 1006.78 hPa (higher than critical threshold)

  5. Evaluate Tide Height:

  6. Day 1: High tide = ~18.44 feet
  7. Day 2: High tide = ~18.06 feet
  8. Day 3: High tide = ~17.64 feet

  9. Consider Wind Direction:

  10. Day 1: NW at 11 kmph (7 mph)
  11. Day 2: S at 9 kmph (6 mph)
  12. Day 3: SSW at 16 kmph (10 mph)

  13. Integrate NOAA High Tide Flooding Likelihood:

  14. All days have a low flood likelihood with a percent chance of 0%.

  15. Synthesize Information and Forecast Flood Category:

  16. Based on the analysis, Days 2 and Day3 are categorized as Category 3 due to moderate risk factors including tide height and wind direction.
  17. Day1 is categorized as Category2 due to slightly lower risk factors compared to Days2 and Days3.

This analysis emphasizes that while there are moderate risks for coastal flooding on Days2 and Days3, the overall likelihood remains low based on current data trends and historical comparisons.
