Hurricane Matthew Overview
What we expected • Hurricane Matthew was an
extremely destructive and long-lived tropical cyclone which became the first Category 5 Atlantic hurricane since Hurricane Felix in 2007.
• It was reclassified as a Post-Tropical Cyclone by the time it entered Virginia
• There were heavy winds and rain but not much storm surge in most areas
• The forecast cone of uncertainty did not show Virginia being impacted, until..
What actually happened … it tracked tightly along the North Carolina coast and headed out to sea just as it reached Virginia • Impacts to the Tidewater
area were primarily from long duration bands of rain on the backside of the cyclone
• The date range of impact was primarily October 8 and 9, with extensive flooding continuing into the 10th and beyond.
Hurricane Matthew – Rainfall Totals • Rainfall totals in the Hampton
Roads area ranged from 3 to 14” inches over 34 hours
• The populated areas of Chesapeake, Hampton, Newport News, Norfolk, Portsmouth, and Virginia Beach were the heaviest hit
• The National Weather Service at Wakefield reported 10 or more inches of rain in a band from Rocky Mount, North Carolina through the Virginia Beach area (https://twitter.com/NWSWakefieldVA, October 9, 2016).
Hurricane Matthew – Rainfall Totals
Pre-Existing Saturated Conditions • Top Image:16 days
prior to Hurricane Matthew (Sept 20 through Oct 5) = 8 to 12 inches
• Bottom Image: 12 day totals including Hurricane Matthew (Oct 6 through Oct 18) = 9 to 12 inches
• Average Annual Rainfall for the area is 46.5 inches
▸ 50% of the annual rainfall fell in 1 month, and 25% in one day
Disaster Declaration • Requested by the
Governor of Virginia on October 7, 2016
• Declared on November 2, 2016
• IA only at first • Amendment One
signed on Nov. 16, 2016
• Added additional IA and PA jurisdictions
Where, how and with whom do we look?
Preliminary Conclusions 1. Pre-Existing saturated conditions throughout the
Tidewater area set the stage for disastrous interior flooding
2. Hurricane (Post-Tropical Storm) Matthew was not a statistically significant storm surge or wave action event along the coastal waterfront despite the damage it caused
3. Several interior areas of Virginia Beach experienced a <1% annual chance flood event during (Canal #2 to London Bridge Creek)
4. There are not enough riverine gages to confirm the annual chance flood event
Preliminary Conclusions (continued)
• The existing storm drainage network cannot handle 50% of the annual rainfall amount in 1 month, and 25% in one day.
• A large percentage of the flooded properties are slab-on-grade.
• Some new developments have been experiencing drainage issues (Ashville Park in Virginia Beach)
