Redondo Beach, WA
CATEGORY 4
WHAT Minor coastal flooding expected. Possible inundation of up to 1 foot above ground level near shorelines and low-lying areas.
WHEN From 9:00 AM to 11:00 AM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
Barometric Pressure: The mean pressure at the time of the high tide on 2025-01-06 at 09:42 AM is 1020.47 hPa. This is higher than pressures observed during historical Category 4 events, suggesting less severe weather conditions.
Tide Height: The predicted tide height is approximately 20.68 feet at peak, which is comparable to historical Category 4 events like the one on 12/18/2024.
Wind Direction and Speed: Winds are from the north at approximately 9 mph. This is lower than wind speeds in previous Category 4 events, indicating a lesser impact from wind-driven water levels.
NOAA High Tide Flooding Likelihood: NOAA indicates a high flood likelihood with an 11.3% chance and a distance to threshold of -0.53 meters. This likelihood is significant and aligns with historical Category 4 events.
Based on these factors, particularly the significant tide height and NOAA's high flood likelihood, a Category 4 flood event is forecasted for Day 1 despite the higher barometric pressure.
CATEGORY 3
WHAT Elevated tides expected. Close monitoring is advised, but significant flooding is unlikely.
WHEN From 10:00 AM to 12:00 PM PST.
IMPACTS Minor flooding of very low-lying areas is possible, but no major property damage is anticipated.
Barometric Pressure: The mean pressure during the high tide at 10:18 AM is 1025.81 hPa, which is significantly higher than during historical flood events, indicating stable atmospheric conditions.
Tide Height: The tide height is expected to reach approximately 20.53 feet, slightly lower than Day 1 and below historical Category 4 thresholds.
Wind Direction and Speed: Wind speeds are low, around 4-5 mph, with directions varying from northeast to north-northeast, suggesting minimal wind-related tidal impact.
NOAA High Tide Flooding Likelihood: NOAA forecasts a high flood likelihood with a 6.8% chance and a distance to threshold of -0.67 meters, which is lower than Day 1.
Considering the high barometric pressure and slightly lower tide heights, Day 2 is assessed as a Category 3 event. While close to a flood event, significant flooding is unlikely.
CATEGORY 2
WHAT Normal tidal conditions expected with no risk of flooding.
WHEN No flood risk anticipated.
IMPACTS No flooding expected. Regular coastal activities can proceed without concern.
Barometric Pressure: The mean pressure at the high tide time of 11:00 AM is 1025.62 hPa, remaining high and indicative of stable weather conditions.
Tide Height: Predicted tide height is approximately 20.29 feet, lower than the previous two days and below historical flood event levels.
Wind Direction and Speed: Winds are light, ranging from 4 to 8 mph, primarily from the north-northeast to northeast, posing no significant impact on tidal conditions.
NOAA High Tide Flooding Likelihood: NOAA indicates a low flood likelihood with a 3.4% chance and a distance to threshold of -0.87 meters, further reducing the risk of flooding.
Based on the combination of high barometric pressure, lower tide heights, and low NOAA flood likelihood, Day 3 is categorized as Category 2, indicating no risk of flooding.
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.
