Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding is possible. High tide levels approaching critical thresholds may lead to minor inundation near shorelines and low-lying areas.
WHEN From 5:30 AM to 7:30 AM PST.
IMPACTS Minor flooding of low-lying areas, beaches, and waterfront parks. Some roads along the coast may experience ponding of water. No significant property damage is expected.
Barometric Pressure: The barometric pressure is around 1003 hPa. This is higher than the pressures recorded during historical Category 4 events but similar to the Category 3 event on 12/27/2023, which had a pressure of 1006.1 hPa.
Tide Height: The high tide at 6:30 AM reaches approximately 20.5 feet. This is higher than the Category 3 event (17.460 ft) but lower than the Category 4 event on 11/15/2021 (21.506 ft).
Wind: Winds are from the south-southwest at about 11 mph. This is less severe than winds in historical higher-category events, which had speeds over 16 mph.
NOAA Flood Likelihood: NOAA indicates a low flood likelihood for this day, with a 3.4% chance and a distance to threshold of -0.77m. This is lower than the 8.4% likelihood in the historical Category 3 event.
Comparison with Historical Events: The combination of moderate barometric pressure and significant tide heights suggests conditions similar to previous Category 3 events. While tides are relatively high, the barometric pressure and NOAA's low flood likelihood indicate that severe flooding is unlikely.
CATEGORY 3
WHAT Minor coastal flooding is possible. Elevated tide levels may lead to minor inundation in low-lying coastal areas.
WHEN From 6:30 AM to 8:00 AM PST.
IMPACTS Minor flooding of low-lying areas along the coast. Beach erosion is possible. No major property damage is expected.
Barometric Pressure: The barometric pressure ranges from 1009 hPa to 1010 hPa during the high tide at 7:24 AM. This is higher than on Day 1, suggesting slightly less severe weather conditions.
Tide Height: The high tide reaches approximately 20.1 feet. This is slightly lower than Day 1 but still significant.
Wind: Winds are light, around 10 mph from the south. Wind conditions are less impactful compared to historical higher-category events.
NOAA Flood Likelihood: NOAA indicates a high flood likelihood for this day, with a 5.2% chance and a distance to threshold of -0.68m. While higher than Day 1, it is still lower than the historical Category 3 event.
Comparison with Historical Events: Despite the higher NOAA flood likelihood, the increased barometric pressure and slightly lower tide height compared to Day 1 suggest that the conditions remain within a Category 3 event. The risk is worth monitoring but significant flooding is unlikely.
CATEGORY 2
WHAT No significant flooding expected. Tide levels are elevated but are not expected to cause inundation.
WHEN Around 7:00 AM PST.
IMPACTS No flooding impacts anticipated. Normal tidal conditions for the area.
Barometric Pressure: The barometric pressure is relatively high at around 1015 hPa during the high tide at 8:18 AM, indicating stable weather conditions.
Tide Height: The high tide reaches approximately 20.3 feet, similar to previous days but with higher barometric pressure reducing the risk.
Wind: Light winds from the southeast at about 6 mph. Minimal impact from wind is expected.
NOAA Flood Likelihood: NOAA indicates a low flood likelihood with a 2.6% chance and a distance to threshold of -0.82m, the lowest among the three days.
Comparison with Historical Events: Given the high barometric pressure and low NOAA flood likelihood, conditions align with a Category 2 event. There is no substantial flood risk under these circumstances.
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.
