Redondo Beach, WA
CATEGORY 4
WHAT Moderate coastal flooding expected. Possible inundation of up to 1-2 feet above ground level near shorelines and low-lying areas.
*WHEN From 6:00 AM to 7:00 AM PST and from 6:00 PM to 7:30 PM PST.
IMPACTS Moderate flooding of low-lying areas, parks, and roads. Isolated road closures possible, with some properties at risk of water intrusion.
The barometric pressure readings for the high tides on this day are significantly higher than the threshold that typically indicates severe weather conditions and potential flooding (1001.8 hPa and 1002.4 hPa respectively). However, the NOAA Flood Likelihood Analysis indicates a high likelihood of flooding at 10.1%, with the tide height nearing the flood threshold but not surpassing it significantly. The wind direction is not provided, but if it were from the W/NW as in past events, it could increase the risk. Comparing this to historical events, particularly the Category 4 event on 11/15/2021 with a lower barometric pressure and higher tide height, suggests that while there is a moderate risk of flooding, it may not reach the most severe levels observed in past Category 4 or 5 events.
CATEGORY 3
WHAT Minor coastal flooding expected. Potential for water accumulation in low-lying areas near shorelines.
WHEN From 7:00 AM to 8:00 AM PST and from 7:30 PM to 8:30 PM PST.
IMPACTS Minor flooding of parks, walkways, and roads close to the shore. Low risk of property damage, but caution advised in flood-prone areas.
On this day, the barometric pressure is much higher (1016.3 hPa and 1028.1 hPa), indicating less severe weather conditions and a lower likelihood of significant flooding compared to historical Category 4 events. The NOAA Flood Likelihood Analysis still classifies the flood likelihood as high but with a lower percentage (7.9%) than on Day 1. The distance to the flood threshold has increased slightly compared to Day 1, suggesting a reduced risk of flooding.
CATEGORY 2
WHAT Low risk of coastal flooding. Normal tidal conditions expected with no significant overflow.
WHEN Throughout the day, particularly during high tides.
IMPACTS No significant impacts anticipated. Regular activities near shorelines can proceed with usual caution.
The barometric pressure remains high (1029.4 hPa), which correlates with stable weather conditions and a very low likelihood of flooding. The NOAA Flood Likelihood Analysis indicates a further decrease in flood likelihood percentage (6.4%) and an increased distance to the flood threshold (-0.41m). This suggests that while there is always a baseline risk due to tidal activity, significant flooding is unlikely on this day.
Residents and visitors 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. Consult local authorities or experts for final decision-making in flood-related situations and adhere to any advisories or evacuation orders that may be issued.
