Hurricane Ivan: Five Years Ago

September 16-17 marks the five year anniversary of Hurricane Ivan, the strongest storm of the 2004 Atlantic Hurricane Season. Ivan made landfall in the early morning hours of September 16 at Gulf Shores, AL with 120mph winds (Cat 3). Ivan's remnants tracked toward the Commonwealth on the 17th, when 40 tornadoes were spawned in Virginia in a single day, including one strong F3 tornado. This holds the record for the most tornadoes in a single day in Virginia! This one day of tornadoes also broke the previous Virginia record for most tornadoes in an entire year: 31 tornadoes in 2003.

Ivan's remnants then passed east of the Commonwealth into the Atlantic, taking an unusual turn southward (see track below). The remnants reorganized after passing southern Florida back into the Gulf, and made a second landfall in Cameron, Louisiana as Tropical Depression Ivan.

We Need The Rain!

It's been very dry over the past two weeks. The majority of the area has seen less than one inch of rainfall.



Rivers and streams are running low, especially to the west of I-95.



Showers will be spotty and mainly light for today and tomorrow, so it doesn't look like we will get that much rain. A larger storm system is headed this way for next week and could potentially bring us more substantial rainfall. Let's keep our fingers crossed!
