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 is significantly higher than the threshold associated with past flooding events, suggesting less severe weather conditions. The high tide at 01:18 with a mean pressure MSL of 1017.1 hPa and at 10:48 with a mean pressure MSL of 1020.7 hPa are both well above the threshold that has historically led to flooding. The NOAA flood likelihood for this day is low, with a likelihood percent of 0.0%, indicating that despite the high tide, the risk of flooding is minimal due to the higher barometric pressure and lack of significant rainfall.
CATEGORY 2
WHAT Minor coastal flooding potential persists with similar conditions as Day 1.
WHEN From 12:00 AM to 11:59 PM PST.
IMPACTS Similar minor impacts as Day 1, with potential for isolated areas to experience brief inundation.
Continued high barometric pressures at times of high tide (02:06 and 17:12) with mean pressures MSL of 1023.8 hPa and 1019.0 hPa respectively, indicate a stable atmosphere less conducive to storm surge and flooding. The NOAA flood likelihood remains low for this day as well, supporting the forecast of minimal flood risk.
CATEGORY 3
WHAT Elevated risk of coastal flooding due to lower barometric pressure and continued high tides.
WHEN Highest risk near times of high tide at approximately 02:36 AM and again at around 01:36 PM PST.
IMPACTS Increased potential for minor property damage in very low-lying areas, with more widespread inundation possible near shorelines and tidal basins.
On this day, the barometric pressure drops closer to the threshold that has historically led to more significant flooding events (high tide at 02:36 with a mean pressure MSL of 1010.4 hPa and at 13:36 with a mean pressure MSL of 1007.0 hPa). While still not as low as during major flood events, this decrease in pressure combined with high tides could lead to more substantial impacts than on the previous days. The NOAA flood likelihood data is not indicating an increased risk, but given the lower pressures observed, there is a slightly higher risk 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.
