Flood Watch

Redondo Beach, WA

Day 1: 2024-09-26

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 11:00 PM to 12:00 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 1016.59 hPa during the high tide at 23:48, which reduces the likelihood of severe flooding. The tide height is significant but not extreme compared to historical events. Wind direction is SSW with speeds around 14 kmph (9 mph), which is not expected to exacerbate flooding conditions significantly.

Day 2: 2024-09-27

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 04:54 AM to 05:54 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 1013.72 hPa during the high tide at 04:54, which reduces the likelihood of severe flooding. The tide height is significant but not extreme compared to historical events. Wind direction is SSW with speeds around 14 kmph (9 mph), which is not expected to exacerbate flooding conditions significantly.

Day 3: 2024-09-28

CATEGORY 3

WHAT Moderate coastal flooding expected. Possible inundation of up to 2 feet above ground level near shorelines and low-lying areas.

WHEN From 01:06 AM to 02:06 AM PST.

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

ADDITIONAL DETAILS...

The barometric pressure is relatively high at 1016.42 hPa during the high tide at 01:06, which reduces the likelihood of severe flooding. However, the tide height is higher than previous days and closer to historical flood events. Wind direction is SSW with speeds around 14 kmph (9 mph), which could contribute slightly to the flood risk.

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:

Day 1 (2024-09-26):

  1. Assess Barometric Pressure:
  2. High tide at 23:48 with a pressure of 1016.59 hPa.

  3. This pressure is significantly higher than in severe flood events.

  4. Evaluate Tide Height:

  5. Tide height is significant but not extreme compared to historical data.

  6. Consider Wind Direction:

  7. Wind direction SSW with speeds around 14 kmph (9 mph).

  8. Not expected to exacerbate flooding significantly.

  9. Integrate NOAA High Tide Flooding Likelihood:

  10. NOAA indicates a low likelihood of flooding for this date.

  11. Synthesize Information:

  12. Given the high barometric pressure and moderate tide height, the flood category for this day is Category 2.
