Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding possible. Slight inundation of low-lying areas near shorelines and tidal waterways.
WHEN From 4:00 AM to 7:00 AM PST on January 14, 2025.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible. No significant property damage expected.
Step 1: Assess Barometric Pressure The barometric pressure during the high tide is approximately 1027.88 hPa, which is significantly higher than pressures observed during severe flood events (e.g., <= 992 hPa). This high pressure indicates stable atmospheric conditions, reducing the likelihood of severe flooding.
Step 2: Evaluate Tide Height The peak tide height is around 20.57 Ft at approximately 5:24 AM. This tide height is similar to historical Category 3 events and suggests a moderate risk of minor coastal flooding.
Step 3: Consider Wind Direction and Speed Wind speeds are light, averaging 4 mph from the NE (36 degrees) during the high tide. This wind direction and speed are not expected to contribute significantly to flooding.
Step 4: Integrate NOAA High Tide Flooding Likelihood NOAA's forecast indicates a High flood likelihood for January 14, with a likelihood percent of 8.2%, a flood threshold of 2.1 meters, and a distance to threshold of -0.63 meters. This suggests that water levels may approach flooding thresholds but are unlikely to cause significant impacts.
Step 5: Synthesize Information and Forecast Flood Category Considering the high barometric pressure, significant tide height, benign wind conditions, and NOAA's forecast, the flood category for January 14 is assessed as Category 3. Conditions are close to a flood event and worth monitoring, but significant flooding is unlikely.

WHAT Minor coastal flooding possible. Slight inundation of low-lying areas near shorelines and tidal waterways.
WHEN From 5:00 AM to 8:00 AM PST on January 15, 2025.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible. No significant property damage expected.
Step 1: Assess Barometric Pressure The barometric pressure during the high tide is approximately 1014.95 hPa, lower than Day 1 but still above the threshold associated with severe historical events. This indicates moderately stable conditions.
Step 2: Evaluate Tide Height The peak tide height is around 20.50 Ft at approximately 6:54 AM, similar to Day 1 and historical Category 3 events.
Step 3: Consider Wind Direction and Speed Wind speeds remain light to moderate, with an average of 4 mph from the NNE (32 degrees). These conditions are not expected to significantly impact flooding potential.
Step 4: Integrate NOAA High Tide Flooding Likelihood NOAA's forecast indicates a High flood likelihood for January 15, with a likelihood percent of 7.2%, a flood threshold of 2.1 meters, and a distance to threshold of -0.66 meters. This is slightly lower than Day 1 but still suggests a moderate risk.
Step 5: Synthesize Information and Forecast Flood Category Given the moderately lower barometric pressure, significant tide height, and NOAA's forecast, the flood category for January 15 remains at Category 3. Conditions are close to a flood event and worth monitoring, but significant flooding is unlikely.
CATEGORY 2
WHAT No risk of flooding expected.
WHEN N/A
IMPACTS No flooding impacts expected.
Step 1: Assess Barometric Pressure The barometric pressure during the high tide is approximately 1022.45 hPa, indicating stable atmospheric conditions.
Step 2: Evaluate Tide Height The peak tide height is around 20.34 Ft at approximately 7:18 AM, slightly lower than previous days and below levels associated with flooding in historical data.
Step 3: Consider Wind Direction and Speed Wind speeds are light, averaging 4 mph from the SSE (161 degrees). This wind direction is not associated with increased flood risk in the area.
Step 4: Integrate NOAA High Tide Flooding Likelihood NOAA's forecast indicates a Low flood likelihood for January 16, with a likelihood percent of 4.2%, a flood threshold of 2.1 meters, and a distance to threshold of -0.81 meters. This suggests water levels are well below flooding thresholds.
Step 5: Synthesize Information and Forecast Flood Category Considering the high barometric pressure, lower tide height, calm wind conditions, and low NOAA flood likelihood, the flood category for January 16 is assessed as Category 2. There is no risk of flooding 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.
