Flooding and Rip Current Concerns from Chantal; Lingering Flood Watches in Central Texas

Chantal is now a Tropical Depression. Flash flood concerns continue across portions of central North Carolina into Monday. Life-threatening surf and rip currents conditions are expected to continue at beaches along the U.S. East Coast from northeastern Florida to the Mid-Atlantic states during the next day or so. Flood Watches and recovery continue across central Texas. Read More >

Overview

Idalia strengthened to a tropical storm about 150 miles SE of Cancun, Mexico on Sunday, August 27th. Idalia then tracked almost due north for 2.5 days and strengthened to a major hurricane Tuesday night/early Wed AM (8/29-30). Idalia made landfall as a Category 3 hurricane by Keaton Beach, FL during the morning of August 30. At the same time, a moderately strong late summer cold front was approaching the region from the north while ~1020mb high pressure built over the Great Lakes. The front crossed the region during the evening of 8/30 to the early morning on 8/31. Tropical Storm Idalia began to interact with the front as it moved off of the northeast South Carolina coast early on 8/31/2023, then continued to track east-northeast through the day. Sustained Tropical Storm winds were observed along the immediate Currituck County coastline, with tropical storm wind gusts reported into Hampton Roads. A peak wind gust of 52 kt was reported from the Third Island Station in the Lower Chesapeake Bay. This station is 52 ft high. In addition, water levels at 2-2.5 MHHW caused some minor beach and dune erosion from Cape Henry south, with some minor coastal flooding in southside Hampton Roads. In addition, water levels in Edenton, NC (on the north side of the Albemarle Sound) rose to nearly 0.6 ft above minor flood thresholds as the northeast wind pushed water toward the western side of the sound. Also, water levels in Westover, NC (Bertie County) rose to 3.28 ft above NAVD88 (although this is below flood stage according to NC FIMAN). See "Tidal Flooding" section for detailed hydrographs from the event. Appreciable rain amounts were confined to far SE VA and NE NC, where 1 to locally 4 inches of rain fell. Flooding issues were minor as rain rates were not that high and antecedent conditions were dry in the areas that received the most rain.
