Redondo Beach, WA
CATEGORY 3
WHAT
Minor coastal flooding possible. Inundation of up to 1 foot above ground level near shorelines and low-lying areas.
WHEN
From 10:00 AM to 12:00 PM PST.
IMPACTS
Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
Barometric Pressure Assessment:
The barometric pressure is 1019.25 hPa during the high tide at 10:42 AM, which is significantly higher than pressures recorded during historical severe flood events (Category 4 and 5) that were below 1002 hPa. This suggests less severe weather conditions.
Tide Height Evaluation:
The maximum tide height is approximately 19.178 ft at 10:42 AM. This is higher than the Category 3 historical event on 12/27/2023 (17.460 ft) but lower than the Category 4 event on 11/15/2021 (21.506 ft). High tide levels over 16 ft, especially when combined with other factors, warrant monitoring.
Wind Direction and Speed:
Winds are light, around 2-4 mph, coming from the south to east-northeast directions. These wind conditions are less likely to contribute significantly to coastal flooding compared to the higher wind speeds and specific wind directions observed in historical flood events.
NOAA High Tide Flooding Likelihood:
NOAA indicates a low flood likelihood for this date with a 0.0% chance and a distance to the flood threshold of -2.0 meters. This suggests minimal risk of flooding from NOAA’s perspective.
Synthesis:
Given the moderate tide height and high barometric pressure, the risk of significant flooding is low but worth monitoring. This aligns with a Category 3 event, which is close to a flood event but unlikely to cause flood damage.

WHAT
Minor coastal flooding possible. Inundation of up to 1 foot above ground level near shorelines and low-lying areas.
WHEN
From 11:00 AM to 1:00 PM PST.
IMPACTS
Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
Barometric Pressure Assessment:
The barometric pressure is 1021.78 hPa during the high tide at 12:00 PM, which is higher than the pressures associated with historical flood events. This indicates stable atmospheric conditions.
Tide Height Evaluation:
The maximum tide height is approximately 19.037 ft at 12:00 PM. Similar to Day 1, this tide height is higher than the historical Category 3 event but remains below the levels associated with more severe flooding.
Wind Direction and Speed:
Winds are light, ranging from 1-3 mph, predominantly from the north. These conditions are not conducive to significant coastal flooding.
NOAA High Tide Flooding Likelihood:
NOAA reports a low flood likelihood with a 0.0% chance and a distance to the flood threshold of -2.13 meters for this date.
Synthesis:
The combination of moderate tide heights, high barometric pressure, and low wind speeds suggests a low risk of significant flooding. Monitoring is advised, consistent with a Category 3 event.
CATEGORY 2
WHAT
No significant flooding expected.
WHEN
N/A
IMPACTS
No substantial flood risk anticipated.
Barometric Pressure Assessment:
The barometric pressure is 1027.15 hPa during the high tides at 12:54 PM and 11:36 PM, which is considerably higher than pressures during any historical flood events. This indicates very stable weather conditions.
Tide Height Evaluation:
The maximum tide height is approximately 18.998 ft at 12:54 PM, slightly lower than the previous two days. This tide height, combined with high barometric pressure, poses minimal flood risk.
Wind Direction and Speed:
Winds remain light, between 1-6 mph, shifting from north-northeast to east-southeast throughout the day. These wind conditions are not expected to contribute to coastal flooding.
NOAA High Tide Flooding Likelihood:
NOAA indicates a low flood likelihood with a 0.0% chance and a distance to the flood threshold of -2.17 meters for this date.
Synthesis:
Given the slightly lower tide heights, very high barometric pressure, and light winds, there is no substantial flood risk anticipated. This aligns with a Category 2 event, representing normal conditions with no 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.
