Flood Watch

Redondo Beach, WA

Day 1: 2024-09-14

CATEGORY 3

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

WHEN From 00:00 AM to 03:00 AM PST and from 03:00 PM to 06:00 PM PST.

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

ADDITIONAL DETAILS...

The high tide at 2024-09-14 15:12 is expected to reach a height of approximately 18.645 feet with a barometric pressure of 1012.82 hPa. This pressure is higher than the critical threshold of 992.8 hPa, reducing the likelihood of severe flooding. However, the tide height is significant enough to warrant monitoring. The wind direction from the south-southwest (170 degrees) at moderate speeds may contribute to minor coastal flooding.

Day 2: 2024-09-15

CATEGORY 3

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

WHEN From 01:00 AM to 04:00 AM PST and from 03:00 PM to 06:00 PM PST.

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

ADDITIONAL DETAILS...

The high tide at 2024-09-15 15:36 is expected to reach a height of approximately 19.003 feet with a barometric pressure of 1010.38 hPa. This pressure is still above the critical threshold, indicating a lower risk of severe flooding. The wind direction from the north (360 degrees) at moderate speeds may slightly increase the risk but not significantly.

Day 3: 2024-09-16

CATEGORY 4

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

WHEN From 02:00 AM to 05:00 AM PST and from 04:00 PM to 07:00 PM PST.

IMPACTS Likely flooding of low-lying areas, parks, and roads. Road closures possible, with potential property damage in vulnerable areas.

ADDITIONAL DETAILS...

The high tide at 2024-09-16 16:00 is expected to reach a height of approximately 19.350 feet with a barometric pressure of 1008.76 hPa. This pressure is approaching the critical threshold, increasing the likelihood of significant coastal flooding. The wind direction from the north-northwest (343 degrees) at moderate speeds may exacerbate the situation, pushing more seawater towards the coast.

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:

  1. Assess Barometric Pressure: The barometric pressure is relatively high at both high tide times (1009.99 hPa and 1012.82 hPa), suggesting less severe weather conditions.
  2. Evaluate Tide Height: The tide heights are significant but not extreme (16.811 ft at midnight and around 18 ft in the afternoon).
  3. Consider Wind Direction: Wind direction from SW (218 degrees) at moderate speeds.
  4. NOAA High Tide Flooding Likelihood: Low likelihood according to NOAA data.
  5. Synthesize Information: Given the high barometric pressure and moderate tide heights, this day is categorized as Category 3.

Day 2:

  1. Assess Barometric Pressure: The barometric pressure remains above critical levels (1010.38 hPa and higher).
  2. Evaluate Tide Height: Tide heights are significant but not extreme (around 19 ft).
  3. Consider Wind Direction: Wind direction from N (360 degrees) at moderate speeds.
  4. NOAA High Tide Flooding Likelihood: Low likelihood according to NOAA data.
  5. Synthesize Information: Given the high barometric pressure and significant tide heights, this day is categorized as Category 3.

Day 3:

  1. Assess Barometric Pressure: The barometric pressure is approaching critical levels (1008.76 hPa).
  2. Evaluate Tide Height: Tide heights are significant (around or above 19 ft).
  3. Consider Wind Direction: Wind direction from NNW (343 degrees) at moderate speeds.
  4. NOAA High Tide Flooding Likelihood: Low likelihood according to NOAA data.
  5. Synthesize Information: Given the lower barometric pressure approaching critical levels and significant tide heights, this day is categorized as Category 4 due to increased flood risk potential.

This analysis provides a comprehensive assessment based on available data, but it is crucial for residents in flood-prone areas to stay updated with local authorities for real-time information and advisories.
