Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding possible. Conditions are close to a flood event, but significant damage is unlikely.
WHEN From 5:00 AM to 7:00 AM PST.
IMPACTS Possible minor flooding in low-lying areas near shorelines and tidal waterways. Some localized road closures could occur.
Forecast Reasoning:
Step 1: Assess Barometric Pressure The barometric pressure is approximately 1018 hPa during the high tide at 5:48 AM, which is higher than in previous severe flood events. This suggests stable weather conditions and a lower likelihood of extreme flooding.
Step 2: Evaluate Tide Height The tide height peaks at approximately 20.6 feet, higher than the historical Category 3 event but below the levels observed in higher category events. This indicates a moderate risk for flooding.
Step 3: Consider Wind Direction and Speed The wind speed is around 8 mph from the south (188 degrees). This is less severe than in higher category events, suggesting a minimal impact on potential flooding.
Step 4: Integrate NOAA High Tide Flooding Likelihood NOAA's forecast indicates a high flood likelihood with a 9.5% chance and a distance to threshold of -0.59 meters. This is slightly higher than the historical Category 3 event, signaling moderate concern.
Step 5: Synthesize Information and Forecast Flood Category Given the higher barometric pressure, significant tide height, and NOAA's flood likelihood, the assessment indicates a Category 3 flood potential for Day 1. While flooding is close to occurring, major property damage is unlikely.
CATEGORY 3
WHAT Minor coastal flooding possible. Conditions are close to a flood event, requiring monitoring, but significant damage is unlikely.
WHEN From 6:00 AM to 8:00 AM PST.
IMPACTS Possible minor flooding in low-lying areas near shorelines and tidal waterways. Some localized road closures could occur.
Forecast Reasoning:
Step 1: Assess Barometric Pressure The barometric pressure is approximately 1022 hPa during the high tide at 6:36 AM, which is higher than the pressures associated with severe flood events. This suggests less severe weather conditions.
Step 2: Evaluate Tide Height The tide height peaks at approximately 20.8 feet, slightly higher than Day 1 but still below the critical 21-foot threshold linked to significant flooding. This suggests a moderate risk.
Step 3: Consider Wind Direction and Speed The wind speed is around 5 mph from the southeast (127 degrees) at 6:00 AM. This is lower than in higher category events, indicating minimal impact from wind.
Step 4: Integrate NOAA High Tide Flooding Likelihood NOAA's forecast shows a high flood likelihood with a 15.1% chance and a distance to threshold of -0.44 meters. This is higher than Day 1 and higher than the historical Category 3 event, but due to the higher barometric pressure, the overall risk remains moderate.
Step 5: Synthesize Information and Forecast Flood Category Considering the high barometric pressure, significant but not extreme tide height, and NOAA's flood likelihood, the assessment suggests a Category 3 flood potential for Day 2.
CATEGORY 3
WHAT Minor coastal flooding possible. Conditions are close to a flood event, requiring monitoring, but significant damage is unlikely.
WHEN From 7:00 AM to 9:00 AM PST.
IMPACTS Possible minor flooding in low-lying areas near shorelines and tidal waterways. Some localized road closures could occur.
Forecast Reasoning:
Step 1: Assess Barometric Pressure The barometric pressure is approximately 1033 hPa during the high tide at 7:18 AM, significantly higher than in past severe flood events. This indicates stable weather conditions with a lower flood risk.
Step 2: Evaluate Tide Height The tide height peaks at approximately 20.7 feet, comparable to Day 1 and Day 2, and below the critical threshold of 21 feet.
Step 3: Consider Wind Direction and Speed The wind speed is around 3 mph from the east (93 degrees) at 6:00 AM, indicating minimal impact on flooding potential.
Step 4: Integrate NOAA High Tide Flooding Likelihood NOAA's forecast indicates a high flood likelihood with a 15.7% chance and a distance to threshold of -0.43 meters, similar to Day 2.
Step 5: Synthesize Information and Forecast Flood Category Given the very high barometric pressure, moderate tide height, and NOAA's forecast, the assessment indicates a Category 3 flood potential for Day 3.
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.
