Flood Watch

Redondo Beach, WA

Day 1: 2024-09-22

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 07:00 AM to 08:24 AM PST.

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

ADDITIONAL DETAILS...

The barometric pressure on 2024-09-22 is relatively high, with the highest tide at 19.037 feet occurring at 19:12 with a mean pressure of 1016.95 hPa. This is significantly higher than the pressure observed during severe flood events. The wind speed is low, and the wind direction does not indicate a significant risk of exacerbating flooding conditions. Historical data suggests that similar conditions have not led to severe flooding in the past.

Day 2: 2024-09-23

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 04:36 AM to 05:30 AM PST.

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

ADDITIONAL DETAILS...

On 2024-09-23, the highest tide is at 20.00 feet occurring at 20:00 with a mean pressure of 1012.45 hPa. This pressure is lower than on Day 1 but still higher than the severe flood events in historical data. The wind speed remains low, and the wind direction does not significantly increase flood risk. NOAA's flood likelihood analysis indicates a low likelihood of flooding for this date.

Day 3: 2024-09-24

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 05:30 AM to 11:12 AM PST.

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

ADDITIONAL DETAILS...

On 2024-09-24, the highest tide is at 18.117 feet occurring at 11:12 with a mean pressure of 1010.5 hPa. This pressure is lower than on previous days but still higher than the severe flood events in historical data. The wind speed remains low, and the wind direction does not significantly increase flood risk. NOAA's flood likelihood analysis indicates a low likelihood of flooding for this date.

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 (2024-09-22):

  1. Barometric Pressure: High (1016.95 hPa)
  2. Tide Height: High (19.037 ft)
  3. Wind Speed: Low
  4. Wind Direction: Not significant
  5. NOAA Flood Likelihood: Low

Given the high barometric pressure and moderate tide height, the flood category is assessed as Category 2.

Day 2 (2024-09-23):

  1. Barometric Pressure: Moderate (1012.45 hPa)
  2. Tide Height: High (20 ft)
  3. Wind Speed: Low
  4. Wind Direction: Not significant
  5. NOAA Flood Likelihood: Low

Given the moderate barometric pressure and high tide height, the flood category is assessed as Category 3.

Day 3 (2024-09-24):

  1. Barometric Pressure: Moderate (1010.5 hPa)
  2. Tide Height: High (18.117 ft)
  3. Wind Speed: Low
  4. Wind Direction: Not significant
  5. NOAA Flood Likelihood: Low

Given the moderate barometric pressure and high tide height, the flood category is assessed as Category 3.


This analysis indicates that while there are some risks of minor to moderate coastal flooding over the next three days, severe flooding is unlikely based on current data and historical comparisons.
