Redondo Beach, WA
CATEGORY 3
WHAT
A higher-than-average morning high tide near 20.55 ft is expected, with barometric pressure around 1024.47 hPa. NOAA indicates a “High” flood likelihood (12.1%), though overall conditions (especially the higher pressure) suggest only minor impacts.
WHEN
Highest risk near the morning high tide (approximately 07:30 AM PST through 10:00 AM PST).
IMPACTS
Minor coastal flooding in low-lying areas possible. Ponding of water along beaches and nearshore roads may occur but is unlikely to cause major property damage.
Historically, Category 3 events often occur with tide heights near or above 20 ft when pressure is moderate to high. Compared to past Category 4 events, the pressure on December 9 is significantly higher (reducing storm surge potential), and winds are relatively light. NOAA’s 12.1% flood likelihood indicates it is close to a flood stage but remains unlikely to produce serious damage.
CATEGORY 3
WHAT
Morning high tide near 20.30 ft with very high barometric pressure (about 1028 hPa) and NOAA reporting a “High” likelihood (5.3%). Despite the “High” label, the combination of high pressure and moderate winds lowers the risk of any significant flooding.
WHEN
Primary concern is during the morning high tide window (approximately 08:00 AM PST to 10:30 AM PST).
IMPACTS
Brief minor flooding could affect vulnerable low-lying spots along the shoreline. Most impacts should be minimal, with little to no property damage anticipated.
Comparisons with past Category 3 events (e.g., tide near 20 ft and pressures above 1020 hPa) show conditions here are similar or slightly more stable (due to even higher barometric pressure). NOAA’s 5.3% flood likelihood is lower than Day 1, reinforcing a moderate concern but no expectation of severe impacts.
CATEGORY 2
WHAT
High tide near 20.07 ft, but extremely high barometric pressure (about 1030.68 hPa) and a “Low” NOAA flood likelihood (1.5%).
WHEN
Peak tide late morning (around 09:30 AM PST to 10:30 AM PST).
IMPACTS
No significant flooding is expected. Only minimal water buildup in usual low-lying coastal stretches, if any.
Although the tide height is still around 20 ft, the higher pressure and NOAA’s very low flood likelihood reduce the chance of coastal flooding. Historically, Category 2 indicates virtually no threat of flood damage, aligning with the strong barometric stability forecasted for December 11.
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.
Categories 1-2: No risk of flooding.
Category 3: Close to a flood event and worth monitoring.
Category 4: Flooding is likely however, it is uncertain if this will cause major property damage.
Category 5: Likely to flood and cause property damage.
Categories 6-7: Extremely high risk of flooding and property damage.
