Redondo Beach, WA
CATEGORY 2
WHAT
No risk of flooding. Tides approach approximately 18.9 ft during the morning high tide (around 06:12), but the barometric pressure remains relatively high (about 1021.56 hPa), meaning conditions are not conducive to coastal flooding.
WHEN
Highest tide expected near 06:12 AM PDT.
IMPACTS
No flooding impacts are expected at this time.
• Compared to historical events where flooding occurred (often at tide heights above 20 ft coupled with low barometric pressures < 1002 hPa), today’s high tide and pressure levels do not indicate a flooding risk.
• NOAA’s Flood Likelihood for March 17 is at 0.0%.
• Winds are light and not from a direction that historically exacerbates surges.
CATEGORY 2
WHAT
No risk of flooding. The morning high tide of about 18.6 ft occurs with a barometric pressure of roughly 1018.69 hPa, well above thresholds historically linked to coastal flooding.
WHEN
Highest tide expected near 06:36 AM PDT.
IMPACTS
No flooding impacts anticipated.
• Despite this moderate tide, comparisons with past Category 4 or 5 events (where tide height exceeded 20 ft and pressure was much lower) show no indication of similar risk levels.
• NOAA Flood Likelihood remains at 0.0% for March 18.
CATEGORY 2
WHAT
No risk of flooding continues. The highest tide is around 07:06 AM PDT at roughly 18.2 ft with a pressure near 1011.02 hPa—still well above dangerously low pressure thresholds.
WHEN
Highest tide expected near 07:06 AM PDT and a midday high tide around 12:18 PM PDT with pressure holding around 1011 hPa.
IMPACTS
No flooding impacts expected.
• Although the barometric pressure is slightly lower than Days 1 and 2, it remains far from the low values observed in severe flood events (which can be below 1002 hPa).
• NOAA forecasts continue to show a 0.0% flood likelihood for March 19.
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.
