Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding is possible. Tidal levels may approach high thresholds but significant flooding is unlikely.
WHEN From 6:00 AM to 8:00 AM PST, around the time of the morning high tide.
IMPACTS Minor inundation of low-lying areas near shorelines. Localized ponding of water in areas that are susceptible during higher tides.
On December 17, barometric pressure is high at 1032.99 hPa, which is significantly above the low-pressure conditions associated with past severe flood events. The expected high tide reaches approximately 20.736 ft at 7:00 AM, which is below the critical 21 ft threshold linked to increased flooding risks. Wind speeds are low at around 3 mph, coming from the southeast, which historically does not contribute to flooding in this area. NOAA's flood likelihood is noted as high with a likelihood percent of 15.7%, but the distance to the flood threshold is -0.43 m, indicating water levels are predicted to stay below flood levels. Compared to the historical Category 3 event on 12/27/2023, current conditions show higher barometric pressure and similar tide heights, suggesting a comparable but manageable risk.
CATEGORY 3
WHAT Minor coastal flooding is possible during high tide periods. Significant flooding is not expected.
WHEN From 5:00 PM to 7:00 PM PST, coinciding with the evening high tide.
IMPACTS Possible minor flooding in very low-lying coastal areas. Unlikely to cause property damage.
On December 18, barometric pressure remains high at 1033.75 hPa, which continues to indicate stable weather conditions. The anticipated high tide is around 20.213 ft at 7:00 AM and slightly lower in the evening. Wind speeds increase moderately to approximately 7 mph, shifting from the south to southwest but are not at levels that have historically contributed to flooding. NOAA's flood likelihood is high at 10.0%, with a distance to the flood threshold at -0.57 m, suggesting water levels will remain below critical levels. When compared to past events like the Category 3 event on 12/27/2023, the higher barometric pressure and similar tide heights indicate a low likelihood of significant flooding.
CATEGORY 2
WHAT No significant flooding is expected.
WHEN No flood-related timing concerns for this day.
IMPACTS No appreciable impacts anticipated.
On December 19, the barometric pressure is at 1029.94 hPa, still well above the low-pressure systems associated with severe flooding events. High tides are expected to be lower than previous days, peaking at approximately 20.205 ft in the morning, which is below the 21 ft concern threshold. Wind speeds are mild at around 4 mph from the southeast, with no significant impact on sea conditions. NOAA's flood likelihood is low at 3.5%, with a distance to the flood threshold of -0.87 m, indicating a minimal risk of flooding. Compared to historical flooding events, conditions on this day do not align with those that have led to flooding in the past.
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.
