Redondo Beach, WA
CATEGORY 3
WHAT Close to a flood event and worth monitoring, but unlikely to cause flood damage. Minor coastal flooding possible with tide levels reaching up to 19.2 feet above mean sea level near shorelines and low-lying areas.
WHEN From 10:00 AM to 1:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible. Water may cover some low-lying sections of shoreline trails and parklands.
Barometric Pressure: The barometric pressure is 1019.13 hPa during the high tide, significantly higher than in historical severe flood events (e.g., 1002 hPa during Category 4 events), indicating less severe weather conditions.
Tide Height: The tide is expected to peak at approximately 19.2 feet at 11:30 AM, higher than the historical Category 3 event (17.460 ft on 12/27/2023) but lower than Category 4 events (e.g., 20.586 ft on 12/18/2024).
Wind Direction and Speed: Winds are from the south at around 10 mph, which is moderate and less than the wind speeds in higher category events (e.g., 21 mph during Category 4 events).
NOAA Flood Likelihood: NOAA's forecast indicates a low flood likelihood with a 0.0% chance and a distance to threshold of -2.05 meters, suggesting minimal concern based on their analysis.
Comparing with historical events, the combination of higher barometric pressure and tide heights below critical levels suggests that while minor coastal flooding is possible, significant flooding is unlikely. Monitoring is recommended, but there is no expectation of major flood damage.
CATEGORY 1
WHAT No risk of flooding expected. Normal tidal conditions anticipated.
WHEN No significant risk periods expected.
IMPACTS No flooding impacts anticipated.
Barometric Pressure: High barometric pressure of approximately 1026.38 hPa during high tide, indicating stable and calm weather conditions.
Tide Height: Tide heights reaching up to approximately 19.0 feet at 12:06 PM, which is lower than both Day 1 and historical flooding events.
Wind Direction and Speed: Light winds from the south at around 5 mph, coupled with moderate rain at times, indicating minimal impact on tidal conditions.
NOAA Flood Likelihood: NOAA indicates a low flood likelihood with a 0.0% chance and a distance to threshold of -2.21 meters, reinforcing the assessment of no flood risk.
Given the high barometric pressure, lower tide heights, and negligible wind influence, there is no risk of flooding for Day 2. Conditions are expected to remain normal without any flood-related concerns.
CATEGORY 3
WHAT Close to a flood event and worth monitoring, but unlikely to cause flood damage. Minor coastal flooding possible with tide levels reaching up to 18.7 feet above mean sea level near shorelines and low-lying areas.
WHEN From 11:00 AM to 2:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible. Water may cover some low-lying sections of shoreline trails and parklands.
Barometric Pressure: The barometric pressure is around 1024.5 hPa during the high tide, which is higher than in historical severe flood events, indicating less severe weather patterns.
Tide Height: The tide is expected to peak at approximately 18.7 feet at 12:42 PM, higher than the historical Category 3 event but below the critical 21-foot level that has been associated with more severe flooding.
Wind Direction and Speed: Winds are from the south-southwest at approximately 20 mph, which is comparable to wind conditions during historical Category 4 events but without the accompanying low barometric pressure.
NOAA Flood Likelihood: NOAA's forecast indicates a low flood likelihood with a 0.0% chance and a distance to threshold of -2.47 meters, suggesting minimal concern.
Despite the higher wind speeds, the elevated barometric pressure and tide heights below critical levels reduce the overall flood risk. While minor coastal flooding is possible, significant flooding is not anticipated. Monitoring is advised due to the wind conditions, but severe flooding is unlikely.
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.
