Affected Areas and Severity of Flooding

This Wednesday Coastal Flood Advisory primarily affects coastal areas of Southeast Pennsylvania. The highest risk of flooding is anticipated in Delaware County and Chester County, with particular concerns for low-lying areas near the Delaware River and Chesapeake Bay. The severity of flooding is predicted to range from minor to moderate, depending on location and the timing of high tide.

• Specific Locations: The most significant impacts are expected in the towns of Chester, Marcus Hook, and Eddystone in Delaware County, and Avondale and Downingtown in Chester County. These areas have a history of flooding during high tides and strong winds.
• Expected Water Levels: Water levels are predicted to rise significantly above normal high tide levels, with potential inundation depths ranging from a few inches to several feet in vulnerable areas. Precise figures will depend on the timing of the high tide and the strength of the wind.
• Vulnerable Areas: Low-lying roads, waterfront properties, and areas with poor drainage are particularly vulnerable. Residents in these areas should take extra precautions.

Timing and Duration of the Coastal Flood Advisory

The Wednesday Coastal Flood Advisory is in effect from 10:00 AM to 4:00 PM EST on Wednesday. The greatest risk of flooding coincides with the high tide, expected around 1:00 PM EST. This period of elevated water levels is anticipated to last for approximately 3-4 hours.

• Periods of Greatest Risk: The hour surrounding the 1:00 PM EST high tide presents the most significant risk of flooding. Remain vigilant during this timeframe.
• Multiple High Tide Cycles: This advisory focuses on a single, significant high tide. However, residents should remain aware of tidal changes throughout the day.
• Potential Updates: The timing and severity of this advisory may be updated. Continue monitoring official weather sources for the latest information.

Associated Weather Conditions

The coastal flooding is primarily attributed to a combination of factors: strong winds, astronomically high tides, and a developing low-pressure system offshore.

• Wind Speeds and Directions: Northeast winds of 20-30 mph are anticipated, with higher gusts possible. These winds will push water towards the coast, exacerbating the effects of the high tide.
• Astronomical Tides: The current phase of the moon contributes to exceptionally high astronomical tides, increasing the baseline water level and amplifying the impact of the wind and storm surge.
• Impact of Weather Systems: A low-pressure system moving off the coast is expected to contribute to stronger than normal winds and higher waves, further increasing the risk of coastal flooding.

Safety Precautions and Recommendations

Residents in affected areas should take the following safety precautions:

• Secure Property and Belongings: Move valuable items to higher ground and consider bringing outdoor furniture and equipment indoors. Protect vulnerable areas from potential water damage.
• Alternative Routes for Travel: Be prepared for potential road closures and plan alternative routes if necessary. Avoid driving through flooded areas; even a few inches of water can cause significant damage to your vehicle.
• Follow Instructions from Local Authorities: Pay close attention to instructions and warnings issued by local emergency management agencies. Evacuate if instructed to do so.
