Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding is possible. Elevated tide levels could lead to inundation of up to 0.5 feet above ground level in low-lying areas near shorelines.
WHEN From 9:00 AM to 12:00 PM PST, with peak conditions around 10:18 AM.
IMPACTS Minor flooding of low-lying areas, including parks and roads adjacent to the shoreline. Isolated road closures are possible.
Step 1: Assess Barometric Pressure The barometric pressure is high at approximately 1025 hPa during the high tide at 10:18 AM. This is significantly higher than pressures observed in historical severe flood events, suggesting less severe weather conditions.
Step 2: Evaluate Tide Height The tide height reaches approximately 20.534 feet at 10:18 AM. This is comparable to the historical Category 3 event on 01/06/2025, which had a tide height of 20.68 feet but with a lower barometric pressure of 1020.47 hPa.
Step 3: Consider Wind Direction and Speed Wind speeds are low, around 2 mph from the SSW (202 degrees). This is less impactful compared to higher wind speeds in past severe events.
Step 4: Integrate NOAA High Tide Flooding Likelihood NOAA forecasts a high flood likelihood of 6.8% with a distance to the flood threshold of -0.67 meters. While this indicates a potential for flooding, the high barometric pressure reduces the overall risk.
Step 5: Synthesize Information and Forecast Flood Category Considering the high barometric pressure, moderate tide height, low wind speed, and NOAA's flood likelihood, the event is categorized as a Category 3 flood risk. Minor flooding is possible, but significant property damage is unlikely.
CATEGORY 2
WHAT No significant flooding expected. Tide levels are elevated but are not likely to cause flooding.
WHEN Peak high tide around 11:00 AM PST.
IMPACTS No expected impacts.
Step 1: Assess Barometric Pressure The barometric pressure is approximately 1029 hPa during the high tide at 11:00 AM, indicating stable and calm weather conditions.
Step 2: Evaluate Tide Height The tide height peaks at about 20.292 feet, which is lower than the tide heights associated with historical flood events.
Step 3: Consider Wind Direction and Speed Wind speeds are minimal, ranging between 1-5 mph, with variable wind directions. This suggests a negligible impact on tidal conditions.
Step 4: Integrate NOAA High Tide Flooding Likelihood NOAA indicates a low flood likelihood of 3.4% with a distance to the flood threshold of -0.87 meters, signifying minimal risk.
Step 5: Synthesize Information and Forecast Flood Category Given the high barometric pressure, lower tide heights, minimal wind impact, and low NOAA flood likelihood, the event is categorized as a Category 2 flood risk. No flooding is expected.
CATEGORY 1
WHAT No flooding expected.
WHEN Peak high tide around 11:00 AM PST.
IMPACTS No expected impacts.
Step 1: Assess Barometric Pressure The barometric pressure is high at approximately 1032 hPa during peak tide times, indicating very stable weather conditions.
Step 2: Evaluate Tide Height Maximum tide height is around 19.991 feet, which is below the levels associated with previous flood events.
Step 3: Consider Wind Direction and Speed Wind speeds are low, between 1-6 mph, with directions primarily from the north and northeast. This has little to no effect on increasing flood risk.
Step 4: Integrate NOAA High Tide Flooding Likelihood NOAA reports a very low flood likelihood of 0.7% with a distance to the flood threshold of -1.19 meters, indicating a negligible risk of flooding.
Step 5: Synthesize Information and Forecast Flood Category With high barometric pressure, lower tide heights, minimal winds, and very low NOAA flood likelihood, the event is categorized as a Category 1 flood risk. No flooding is expected.
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.
