Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding expected. Possible inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.
*WHEN From 6:00 AM to 9:00 AM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure is significantly higher than the threshold associated with past flooding events, suggesting less severe weather conditions. However, the high tide at 07:00 with a mean pressure MSL of 1033.0799560546875 hPa indicates a potential for minor coastal flooding, especially in conjunction with the forecasted weather conditions including light rain and drizzle. The wind direction from the south may contribute to water levels but is not as critical as a W/NW direction would be. Comparing with historical events, the risk is lower than the Category 4 and 5 events but warrants monitoring due to the high tide.
CATEGORY 2
WHAT Low risk of coastal flooding. No significant inundation expected.
WHEN Throughout the day.
IMPACTS No significant impacts expected. Normal tidal conditions with no substantial overflow.
The barometric pressure remains high, reducing the likelihood of severe weather conditions that could lead to flooding. The high tides at 07:24 and 20:30 have mean pressures well above the critical threshold, and NOAA's flood likelihood analysis indicates a low chance of flooding for this date. Wind conditions are not provided but are assumed to be non-critical based on available data.
CATEGORY 4
WHAT Likely to experience coastal flooding with potential property damage.
WHEN High tide events at approximately 07:48 and again at 21:30 PST.
IMPACTS Potential for moderate flooding of properties, especially in low-lying areas near the shoreline. Risk of road closures and disruption to daily activities.
The barometric pressure has dropped significantly to a mean pressure MSL of 1019.8499755859375 hPa during both high tides, which is closer to the threshold associated with previous Category 4 events. This drop in pressure, combined with high tide levels, increases the risk of flooding compared to previous days. The NOAA flood likelihood remains low; however, given the historical data and significant change in pressure, there is an increased risk that needs close monitoring.
Residents and businesses near shorelines and low-lying areas 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.
