While Isaac continues to break down and weaken, the tornado threat associated with the storm is expected to carry on through Thursday evening.
Parts of Mississippi have been under a tornado watch since early Tuesday, when Tropical Storm Isaac first began to impact the state.
Spiral rain-bands around Isaac have prompted the National Weather Service (NWS) to issue dozens of tornado warnings and several tornadoes have been reported.
According to the NWS, at least eight possible tornadoes have hit parts of the state so far including three early Thursday and five on Wednesday.
The public reported numerous trees uprooted and downed in the Stonewall area of Clarke County by a possible tornado early Thursday (5:10 a.m.).
Another possible tornado was reported early Thursday (8 a.m.) near Meridian by emergency management with multiple trees downed.
Jackson County Emergency Management reported a tornado touched down on Market Street in Pascagoula early Thursday (7:16 a.m.)
Law enforcement reported structural damage in the Orange Grove area of Harrison County early Wednesday afternoon (12:33 p.m.) off Highway 49, believed to be caused by a tornado.
Emergency manager later reported the roof was blown off a grocery store in the McHenry area of Stone County Wednesday afternoon (1:37 p.m.). It was first believed to be caused by a tornado, but later believed to be straight-line wind damage.
The Gulfport Police Department reported significant damage caused by a tornado to several homes in the vicinity of 17th Street and 19th Avenue in Harrison County Wednesday evening (5:21 p.m.).
“There was definite damage to three homes close to each other,” said Butch Oberhoff, public affairs officer for Harrison County Emergency Management.
“On one, it looks like it tore the porch off. The two others had significant damage,” Oberhoff said.
Two houses on East Simmons Bayou in Gulf Park Estates sustained damage in a tornado that struck Ocean Springs Wednesday evening (7:30 a.m.), according to Jackson County Sheriff Mike Byrd.
Byrd said there were no injuries reported.
“There’s extensive damage at two houses,” Byrd said.
“There’s a roof off one house and a shed was taken away from another one,” he added.
Emergency manager also reported a possible tornado caused damage in Greene County Wednesday night (9:40 p.m.) with debris thrown onto Bradley Road, three miles southeast of Sand Hill Road.
A tornado watch is in effect through Thursday evening for much of the state.
The watch covers 53 out of the state’s 82 counties until 10 p.m. including Attala, Choctaw, Copiah, Hinds, Holmes, Humphreys, Leake, Madison, Rankin, Scott, Simpson, Smith, Yazoo, Clarke, Jasper, Kemper, Lauderdale, Neshoba, Newton, Noxubee, Winston, Carroll, Grenada, Leflore, Montgomery, Webster, Clay, Lowndes, Oktibbeha, Jefferson Davis, Lawrence, Lincoln, Marion, Covington, Forrest, Jones, Lamar, Washington, Warren, Sunflower, Sharkey, Jefferson, Issaquena, Franklin, Claiborne, Bolivar, Adams, Hancock, Harrison, Jackson, Pearl River, Pike and Walthall.
This could be the biggest day for tornado activity with Isaac so far. The Storm Prediction Center says there is a 60 percent chance of two or more tornadoes within the watch area today.
Everyone is urged to stay updated on the latest weather information as it becomes available.
Tornado watches are routinely issued for the northeast quadrant of land-falling tropical storms and hurricanes.
The results of enhanced speed and directional wind shear in this quadrant with rain-bands around tropical systems, typically leads to quick spin-up, primarily weak tornadoes.
