Redondo Beach, WA
CATEGORY 2
WHAT Minor coastal flooding expected due to high tides, but current barometric pressure suggests less severe weather conditions. Possible inundation of low-lying areas near shorelines.
WHEN High risk from 01:12 AM to 03:00 AM PST and again from 01:24 PM to 03:30 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The high tide at 01:12 AM with a mean pressure MSL of 1007.7 hPa is not indicative of severe flooding, especially when compared to historical Category 4 and 5 events which had significantly lower pressures. The second high tide at 03:24 PM is also under less threatening conditions with a pressure of 1014.8 hPa. NOAA's Flood Likelihood Analysis indicates a low likelihood of flooding for this day.
CATEGORY 3
WHAT Elevated risk of coastal flooding due to high tide and slightly lower barometric pressure. Potential for water encroachment into more susceptible areas.
WHEN High risk from 01:48 AM to 03:30 AM PST and again from 04:24 PM to 06:00 PM PST.
IMPACTS Increased potential for minor property damage and flooding of roads, especially in low-lying areas. Residents should be prepared for possible detours or delays.
The high tide at 01:48 AM with a mean pressure MSL of 1014.2 hPa is slightly concerning when compared to the Category 3 event from historical data, which had a higher pressure. The second high tide at 04:24 PM with a mean pressure MSL of 1009.4 hPa is closer to the threshold that historically indicates potential for flooding, warranting closer monitoring.
CATEGORY 4
WHAT Likely coastal flooding due to high tide and significantly lower barometric pressure. Expect water intrusion into vulnerable areas with potential property damage.
WHEN High risk from 02:24 AM to 04:00 AM PST and again from 12:24 PM to 02:00 PM PST.
IMPACTS Likely flooding of roads, properties, and infrastructure in low-lying coastal areas. Residents should prepare for possible evacuations and protect their properties.
The high tide at 02:24 AM with a mean pressure MSL of 1005.3 hPa is approaching the conditions similar to Category 4 historical events, indicating a higher risk of flooding. The second high tide at 12:24 PM with a mean pressure MSL of just over the threshold at 1002.5 hPa increases the likelihood of significant flooding, especially when considering the wind direction from historical events that led to flooding.
Residents 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 follow any evacuation orders or safety instructions as issued by emergency services.
