Flood Watch

Redondo Beach, WA

Day 1: 2024-08-28

CATEGORY 2

WHAT No significant coastal flooding expected. Conditions are stable with no immediate risk of flooding.

WHEN Throughout the day, with no specific high-risk period identified.

IMPACTS No expected impacts. Normal conditions for low-lying areas, parks, and roads.

ADDITIONAL DETAILS...

The barometric pressure on 2024-08-28 is significantly higher than the threshold for flood risk (1008.56 hPa at 14:30 and 1008.35 hPa at 23:48). The tide heights are also below the critical levels observed in historical flood events. Wind speeds are low, and the wind direction does not indicate any significant risk. NOAA's flood likelihood analysis also indicates a low likelihood of flooding for this date.

Day 2: 2024-08-29

CATEGORY 3

WHAT Close to a flood event but unlikely to cause significant damage. Monitoring is advised.

WHEN Highest risk period around 15:24 PST.

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

ADDITIONAL DETAILS...

On 2024-08-29, the barometric pressure is lower (1005.09 hPa at 15:24 and 1004.98 hPa at 09:24) compared to the previous day but still above the critical threshold of 992.8 hPa. The tide heights are higher than on Day 1 but still below the levels seen in Category 4 or higher events. Wind speeds remain moderate, and the wind direction does not significantly increase flood risk. NOAA's flood likelihood analysis continues to show a low likelihood of flooding.

Day 3: 2024-08-30

CATEGORY 3

WHAT Close to a flood event but unlikely to cause significant damage. Monitoring is advised.

WHEN Highest risk period around 16:06 PST.

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

ADDITIONAL DETAILS...

On 2024-08-30, the barometric pressure continues to decrease (1004.37 hPa at 16:06 and 1005.87 hPa at 01:00), approaching but still above the critical threshold of 992.8 hPa. The tide heights are higher than on previous days but still below the levels seen in Category 4 or higher events. Wind speeds remain moderate, and the wind direction does not significantly increase flood risk. NOAA's flood likelihood analysis continues to show a low likelihood of flooding.

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 (2024-08-28):

  1. Barometric Pressure: High (1008.56 hPa and 1008.35 hPa), indicating stable weather conditions.
  2. Tide Height: Below critical levels observed in historical flood events.
  3. Wind Direction: Low impact on potential flooding.
  4. NOAA Flood Likelihood: Low likelihood of flooding.

Day 2 (2024-08-29):

  1. Barometric Pressure: Lower than Day 1 (1005.09 hPa and 1004.98 hPa) but still above critical threshold.
  2. Tide Height: Higher than Day 1 but below critical levels.
  3. Wind Direction: Moderate impact on potential flooding.
  4. NOAA Flood Likelihood: Low likelihood of flooding.

Day 3 (2024-08-30):

  1. Barometric Pressure: Decreasing further (1004.37 hPa and 1005.87 hPa) but still above critical threshold.
  2. Tide Height: Higher than previous days but below critical levels.
  3. Wind Direction: Moderate impact on potential flooding.
  4. NOAA Flood Likelihood: Low likelihood of flooding.

Based on this analysis, Days 2 and 3 are categorized as Category 3 due to lower barometric pressure and higher tide heights compared to Day 1, which remains Category 2 with no significant flood risk expected.

Always consult local authorities or experts for final decision-making in flood-related situations for safety and accuracy in assessments.
