The National Hurricane Center begin issuing statements on a disturbance east of the Lesser Antilles on August 17th.  It quickly developed into Tropical Storm Harvey by that afternoon.  Harvey weakened back into a depression on Saturday, August 19th.  Harvey remained a depression while it crossed the Caribbean Sea and across the Yucatan Peninsula. Harvey regained Tropical Storm status on early Thursday, August 24th, over the southwest Gulf of Mexico.  Harvey begin to track northwest and quickly become a hurricane by that afternoon.  Harvey become a Category 3 hurricane on Friday, August 25th, and briefly reached Category 4 status before moving inland Friday night near Port Aransas, Texas.  Harvey moved inland and became stationary near the Texas Coast for several days, producing catastrophic flooding along the upper Texas coast with rainfall amounts of 30-50 inches. Harvey moved back over the water briefly before moving back inland over southwest Louisiana on Wednesday, August 30th

The remnants of Harvey tracked northeast along the Mississippi River over the next few days and produced a couple days of heavy rainfall over portions of Central Alabama, but thankfully, it only led to some minor flooding.   On Thursday, August 31st, several feeder bands on the east side of Harvey tracked northeast across west Central Alabama and produced four tornadoes. Additional tornadoes touched down across portions of Texas, Louisiana, Mississippi and Tennessee between August 26th and August 31st. Below are links to the write ups for the tornadoes and other additional data from Harvey.
