Redondo Beach, WA
CATEGORY 2
WHAT Minor coastal flooding expected. Possible inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.
*WHEN From 12:00 AM to 11:59 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure readings for the high tides on this day are well above the threshold that has historically indicated severe flooding events. With pressures of 1004.95 hPa and 1004.69 hPa, the likelihood of a major flood event is reduced despite the high tide levels. The NOAA Flood Likelihood Analysis also indicates a low likelihood of flooding with a 0.0% chance, which supports the forecast of a lower category flood event. Wind direction and speed are not provided but would be considered if they were available.
CATEGORY 2
WHAT Minor coastal flooding potential persists with slight inundation possible in vulnerable areas.
WHEN From 12:00 AM to 11:59 PM PST.
IMPACTS Similar to Day 1, expect minor nuisance flooding in susceptible regions, with no significant property damage anticipated.
On this day, the barometric pressure readings during high tides are higher than on Day 1, at 1005.25 hPa and 1008.54 hPa respectively, suggesting even less risk of severe weather conditions that could lead to flooding. The NOAA Flood Likelihood Analysis continues to show a low likelihood of flooding with a 0.0% chance, reinforcing the expectation of minimal flood impact.
CATEGORY 3
WHAT Elevated risk of coastal flooding due to higher tide levels and lower barometric pressure compared to previous days.
WHEN High tide at approximately 02:06 PM PST poses the greatest risk.
IMPACTS Potential for moderate flooding in low-lying areas and near shorelines. Some property damage is possible if preventative measures are not taken.
The barometric pressure during high tides on Day 3 shows a decrease compared to previous days, with readings of 1015.17 hPa and 1012.85 hPa, which is closer to historical events that have resulted in flooding. However, these values are still above the critical threshold observed in past significant flood events. The NOAA Flood Likelihood Analysis maintains a low likelihood rating for this day as well, but due to the lower pressures and higher tide levels than previous days, there is an increased risk of flooding compared to Days 1 and 2.
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 adhere to any advisories or evacuation orders that may be issued.
