Redondo Beach, WA
CATEGORY 3
WHAT Close to a flood event and worth monitoring, but unlikely to cause flood damage. Minor coastal flooding is possible due to high tides.
WHEN From 3:00 AM to 5:00 AM PST.
IMPACTS Minor flooding of low-lying areas and waterfront parks is possible. Some roads near the shore may experience minor water accumulation.
Step 1: Assess Barometric Pressure The barometric pressure at the time of the high tide is 1006.79 hPa. This pressure is similar to the historical Category 3 event on 12/27/2023 (1006.1 hPa), suggesting stable weather conditions that are not indicative of severe flooding.
Step 2: Evaluate Tide Height The tide height is approximately 17.914 Ft at 4:06 AM. This is slightly higher than the historical Category 3 event (17.460 Ft) but lower than the Category 4 events (over 19 Ft), indicating a moderate risk level.
Step 3: Consider Wind Direction and Speed Wind speeds are low, around 2-4 km/h (1-2 mph), coming from the ESE direction (wind direction degree 107). These conditions are less severe compared to historical higher-category events with stronger winds and do not significantly contribute to an increased flood risk.
Step 4: Integrate NOAA High Tide Flooding Likelihood NOAA's forecast indicates a low flood likelihood of 0.0%, with a distance of -2.37 meters to the flood threshold. This suggests that significant flooding is unlikely based on NOAA's metrics.
Step 5: Synthesize Information and Forecast Flood Category Considering the moderate tide height, normal barometric pressure, minimal wind impact, and NOAA's low flood likelihood, the conditions are consistent with a Category 3 event. It is close to a flood event and worth monitoring, but significant flooding or property damage is unlikely.
CATEGORY 3
WHAT Close to a flood event and worth monitoring, but unlikely to cause flood damage. Minor coastal flooding remains possible due to elevated tides.
WHEN From 4:00 AM to 6:00 AM PST.
IMPACTS Minor flooding of low-lying coastal areas and waterfront pathways is possible. Localized water accumulation may occur on roads adjacent to the shore.
Step 1: Assess Barometric Pressure The barometric pressure during the high tide is 1007.92 hPa. This is slightly higher than Day 1 and remains above the pressures associated with severe flood events, indicating stable atmospheric conditions.
Step 2: Evaluate Tide Height The tide reaches approximately 18.687 Ft at 4:48 AM, which is higher than Day 1 and the historical Category 3 event but still below the heights recorded during Category 4 and 5 events. This elevates the risk slightly but not enough to indicate severe flooding.
Step 3: Consider Wind Direction and Speed Wind speeds are low to moderate, around 4 km/h (2 mph), from the SE direction (wind direction degree 145). The wind conditions are not severe and are less likely to contribute to significant coastal flooding.
Step 4: Integrate NOAA High Tide Flooding Likelihood NOAA's forecast continues to show a low flood likelihood of 0.0%, with a distance of -2.48 meters to the flood threshold, indicating that flooding is unlikely based on their analysis.
Step 5: Synthesize Information and Forecast Flood Category The slight increase in tide height is noted, but with stable barometric pressure, minimal wind impact, and NOAA's low flood likelihood, the overall risk remains consistent with a Category 3 event. Monitoring is advised, but significant flooding is not expected.
CATEGORY 3
WHAT Close to a flood event and worth monitoring, but unlikely to cause flood damage. Elevated tides may cause minor coastal impacts.
WHEN From 2:00 PM to 4:00 PM PST.
IMPACTS Possible minor flooding in low-lying coastal areas and waterfront parks during high tide. Minimal impact on coastal infrastructure is anticipated.
Step 1: Assess Barometric Pressure The barometric pressure is higher on this day, at 1010.87 hPa during the high tide at 3:00 PM. This higher pressure suggests even more stable weather conditions compared to the previous days, reducing the likelihood of severe weather-induced flooding.
Step 2: Evaluate Tide Height The tide height is approximately 18.512 Ft, comparable to Day 2. While the tide remains elevated, it is still below levels associated with significant flooding in historical events.
Step 3: Consider Wind Direction and Speed Wind speeds are low, around 3 km/h (2 mph), coming from the NNE direction (wind direction degree 12). The low wind speed and direction do not contribute significantly to coastal flooding risk.
Step 4: Integrate NOAA High Tide Flooding Likelihood NOAA's forecast maintains a low flood likelihood of 0.0%, with a distance of -1.94 meters to the flood threshold. Despite the slightly smaller distance to the threshold, the likelihood of flooding remains low.
Step 5: Synthesize Information and Forecast Flood Category Given the high barometric pressure, consistent tide heights, low wind speeds, and NOAA's low flood likelihood, the conditions align with a Category 3 event. It is worth monitoring due to the elevated tides, but significant flooding is not anticipated.
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.
