Volusia County Flooding
May 18-23, 2009
May 24, 2009 (Lake George Boating Tragedy)
|
A cold front brought deep moisture to the northern peninsula on Monday, May 18th, and a swath of locally heavy rain accompanied the front with rainfall amounts of 4 to 8 inches recorded across Volusia county by Tuesday morning. Persistent onshore flow behind the front strengthened Tuesday (19th) as low pressure began to form over the Florida Straits, keeping periods of heavy rainfall across much of East Central Florida. Gale conditions (see marine summary below) occurred over the coastal waters Tuesday night. The low pressure center on Wednesday morning (20th) moved to offshore the Florida southwest coast and the wind flow decreased, but strong small craft advisory conditions continued over the coastal waters. Deep moisture and onshore flow allowed showers and thunderstorms to develop and drop more heavy rainfall across coastal areas and northern portions of East Central Florida. This moist pattern with locally heavy rain persisted through Friday (22nd) as the low pressure center moved slowly west to northwest in the Gulf of Mexico. For the week of May 17th through 23rd, Daytona Beach International Airport reported 20.63 inches of rainfall. A CoCoRahs rainfall observer in Ormond Beach measured even more rainfall -- 27.06 inches during this same week. The Daytona Beach rainfall set a May rainfall record by a wide margin (12.66 inches in May 1976 was the previous monthly record for May). The persistent rainfall across Volusia county caused extensive flooding of some neighborhoods across Northeast Volusia county including Ormond Beach and Daytona Beach.
