Redondo Beach, WA
CATEGORY 2
WHAT Minor coastal flooding expected. Possible inundation of up to 1 foot above ground level near shorelines and low-lying areas.
*WHEN From 05:00 AM to 07:00 AM PST and from 05:00 PM to 07:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
On September 19, the high tide at 05:12 AM is expected to reach a height of approximately 19.034 feet with a barometric pressure of 1019.1 hPa. The second high tide at 05:24 PM will reach around 20.051 feet with a barometric pressure of 1023.9 hPa. Both high tides are accompanied by relatively high barometric pressures, which reduces the likelihood of severe flooding. Wind speeds are low, ranging from 1 to 9 kmph, and wind directions vary from NE to SW, which is not expected to significantly exacerbate flooding conditions.

WHAT Minor coastal flooding expected. Possible inundation of up to 1 foot above ground level near shorelines and low-lying areas.
WHEN From 06:00 AM to 08:00 AM PST and from 06:00 PM to 08:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
On September 20, the high tide at 06:12 AM is expected to reach a height of approximately 19.063 feet with a barometric pressure of 1022.4 hPa. The second high tide at 06:00 PM will reach around 19.977 feet with a barometric pressure of 1023.5 hPa. Similar to the previous day, the high barometric pressures reduce the likelihood of severe flooding despite the significant tide heights. Wind speeds remain low, ranging from 4 to 9 kmph, with wind directions primarily from the SSW and NNE.
CATEGORY 3
WHAT Moderate coastal flooding possible. Inundation of up to 2 feet above ground level near shorelines and low-lying areas.
WHEN From 07:00 AM to 09:00 AM PST and from 07:00 PM to 09:00 PM PST.
IMPACTS Moderate flooding of low-lying areas, parks, and roads. Some road closures possible.
On September 21, the high tide at 07:12 AM is expected to reach a height of approximately 18.944 feet with a barometric pressure of 1018.9 hPa. The second high tide at 06:36 PM will reach around 19.649 feet with a barometric pressure of the same value (1018.9 hPa). The slightly lower barometric pressure compared to previous days increases the risk of moderate flooding, especially during the evening high tide when wind speeds are expected to be higher (up to around 10 kmph) with wind directions primarily from the NNW.
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.
This analysis indicates that while minor coastal flooding is expected on September 19 and September 20 (Category 2), there is a moderate risk on September 21 (Category 3) due to slightly lower barometric pressures and higher tide levels in combination with increased wind speeds from potentially impactful directions (NNW). Always consult local authorities or experts for final decision-making in flood-related situations.
