Flood Watch

Redondo Beach, WA

Day 1: 2024-09-25

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 12:00 PM to 02:00 PM PST.

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

ADDITIONAL DETAILS...

The high tide at 12:42 PM on 2024-09-25 is expected to reach a height of 18.201 feet with a barometric pressure of 1017.02 hPa. The wind direction is SSW with speeds around 14 kmph (9 mph). Historical data indicates that similar conditions have not led to significant flooding events. The NOAA flood likelihood for this date is low, with a likelihood percent of 0.0% and a distance to threshold of -2.67m.

Day 2: 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 01:00 AM PST.

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

ADDITIONAL DETAILS...

The high tide at 11:48 PM on 2024-09-26 is expected to reach a height of 17.549 feet with a barometric pressure of 1017.45 hPa. The wind direction is SW with speeds around 13 kmph (8 mph). Historical data indicates that similar conditions have not led to significant flooding events. The NOAA flood likelihood for this date is low, with a likelihood percent of 0.0% and a distance to threshold of -2.41m.

Day 3: 2024-09-27

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 02:00 PM to 04:00 PM PST.

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

ADDITIONAL DETAILS...

The high tide at 02:42 PM on 2024-09-27 is expected to reach a height of 18.589 feet with a barometric pressure of 1014.23 hPa. The wind direction is NNW with speeds around 11 kmph (7 mph). Historical data indicates that similar conditions have led to moderate flooding events in the past, particularly when the barometric pressure was lower than usual. The NOAA flood likelihood for this date is low, with a likelihood percent of 0.0% and a distance to threshold of -2.28m.

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:

Day 1 (2024-09-25):

  1. Barometric Pressure: The pressure is relatively high at 1017 hPa.
  2. Tide Height: The tide height is significant but not extreme at 18.201 feet.
  3. Wind Direction: SSW winds at moderate speeds.
  4. NOAA Likelihood: Low likelihood of flooding.
  5. Historical Comparison: Similar conditions have not led to significant flooding in the past.

Day 2 (2024-09-26):

  1. Barometric Pressure: The pressure remains high at 1017.45 hPa.
  2. Tide Height: The tide height is significant but not extreme at 17.549 feet.
  3. Wind Direction: SW winds at moderate speeds.
  4. NOAA Likelihood: Low likelihood of flooding.
  5. Historical Comparison: Similar conditions have not led to significant flooding in the past.

Day 3 (2024-09-27):

  1. Barometric Pressure: The pressure is slightly lower at 1014.23 hPa.
  2. Tide Height: The tide height is significant at 18.589 feet.
  3. Wind Direction: NNW winds at moderate speeds.
  4. NOAA Likelihood: Low likelihood of flooding.
  5. Historical Comparison: Similar conditions have led to moderate flooding in the past when barometric pressure was lower than usual.

Based on the provided data and applying the Forecast Reasoning steps, the flood categories for the given conditions are predicted as follows: - Day 1: Category 2 - Day 2: Category 2 - Day 3: Category 3

The higher barometric pressures on Days 1 and 2 suggest less severe weather conditions, reducing the likelihood of more severe flood categories despite significant tide heights.
