Redondo Beach, WA
CATEGORY 3
WHAT
A high tide is expected to reach around 20.7 ft late in the morning on December 8, with strong southerly winds. Barometric pressure will remain relatively high (about 1023.5 hPa). Although NOAA’s Flood Likelihood is listed as “High” at 20%, the overall conditions suggest this is unlikely to cause major coastal flood damage. This event is close to a flood threshold and worth monitoring, but significant impacts are not anticipated.
WHEN
Highest risk near the time of morning high tide (roughly 07:30 AM PST to 08:30 AM PST).
IMPACTS
• Minor flooding of very low-lying areas, especially if local wind patterns temporarily push water ashore.
• Occasional ponding of water on roads close to the shoreline.
• Little to no structural damage expected.
• The barometric pressure of around 1023.5 hPa is notably higher than in past severe flood events, reducing potential storm surge.
• Tide levels are comparable to some past Category 3 events (e.g., 01/06/2025 had tide ~20.68 ft at ~1020 hPa).
• NOAA indicates a 20% flood likelihood, but historical comparisons suggest major impacts are unlikely at these pressure levels.
CATEGORY 3
WHAT
High tide is expected to approach approximately 20.5 ft during the morning of December 9. Barometric pressure is forecast to be even higher (~1024.7 hPa), which generally lowers the chance of a significant flood event. NOAA’s Flood Likelihood is 12.1%, so while conditions should be observed, major flood damage is still not anticipated.
WHEN
Highest risk near the time of morning high tide (around 08:30 AM PST to 09:30 AM PST).
IMPACTS
• Potential for brief minor flooding in the most vulnerable low-lying spots.
• No widespread property damage expected.
• Local inundation could impact parks and roads near the shoreline.
• Historically, tides around 20 ft combined with pressures well above ~1016 hPa have led only to minor flooding (often categorized as Category 3).
• NOAA’s reduced likelihood relative to Day 1 suggests a diminishing risk through December 9.
CATEGORY 3
WHAT
A morning high tide near 20.3 ft is expected on December 10, with barometric pressure predicted around 1027 hPa. Although significantly above typical flood thresholds in terms of tide height, the very high atmospheric pressure helps keep surge effects in check. NOAA’s reported 5.3% flood likelihood, which remains worth monitoring but suggests even lower probability of damaging flooding.
WHEN
Peak high tide and minor flood concern likely between 09:00 AM PST and 10:00 AM PST.
IMPACTS
• Minor shoreline flooding possible along beaches or in isolated low-lying spots.
• No major property damage is expected; any flooding would be brief and shallow.
• This tide height is similar to other borderline flood events; however, the unusually high pressure near 1027 hPa reduces the risk of more extensive flooding.
• Recent historical events with lower barometric pressures at similar tide heights (e.g., around 1020 hPa) have been categorized as Category 3, aligning with today’s forecast.
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.
• Categories 1-2: No risk of flooding.
• Category 3: Close to a flood event and worth monitoring.
• Category 4: Flooding is likely however, it is uncertain if this will cause major property damage.
• Category 5: Likely to flood and cause property damage.
• Categories 6-7: Extremely high risk of flooding and property damage.
