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

*WHEN From 05:48 AM to 06:12 PM PST.

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

ADDITIONAL DETAILS...

On September 5th, the high tide at 05:48 AM is expected to reach a height of 17.555 feet with a barometric pressure of 1008.57 hPa. The second high tide at 06:12 PM will reach a height of 18.823 feet with a barometric pressure of 1011.27 hPa. These conditions are similar to the Category 3 event on 12/27/2023, which had a tide height of 17.460 feet and a barometric pressure of 1006.1 hPa. The wind direction is from the WNW, which could exacerbate flooding conditions by pushing more seawater towards the coast.

Forecast Reasoning:

Step-by-step analysis for each day:

DayInfo1 (2024-09-05):

  1. Barometric Pressure:
  2. Morning high tide (05:48 AM): Pressure = 1008.57 hPa.
  3. Evening high tide (06:12 PM): Pressure = 1011.27 hPa.
  4. Both pressures are higher than the critical threshold (992.8 hPa), indicating less severe weather conditions.

  5. Tide Height:

  6. Morning high tide = 17.555 feet.
  7. Evening high tide =18.823 feet.
  8. These heights are significant but not extreme compared to historical Category events.

  9. Wind Direction:

  10. WNW direction could push seawater towards the coast, increasing flood risk slightly.

  11. NOAA High Tide Flooding Likelihood:

  12. Low likelihood (0%) for this date.

  13. Synthesis:

  14. Given the higher barometric pressures and significant but not extreme tide heights, combined with NOAA's low flood likelihood, this day is categorized as Category 3.

DayInfo2 (2024-09-06):

  1. Barometric Pressure:
  2. Morning high tide (06:36 AM): Pressure =1006 .24 hPa.
  3. Evening high tide (06:36 PM): Pressure =1012 .18 hPa.
  4. Both pressures are higher than the critical threshold (992 .8 hPa), indicating less severe weather conditions.

  5. Tide Height:

  6. Morning high tide =17 .507 feet.
  7. Evening high tide =18 .695 feet.
  8. These heights are significant but not extreme compared to historical Category events.
