( CNN ) -- A huge plume of black smoke soared above the picturesque Georgia city of Savannah on Saturday afternoon , prompting officials to urge people to stay inside to avoid the fumes . The fire began around 11:30 a.m. inside a warehouse located in the Georgia Port Authority 's Ocean Terminal , just west off of the city 's historic riverfront , said Savannah Fire Department spokesman Mark Keller . The warehouse contains pallets of solid rubber that were burning , according to Keller . Crews had contained the blaze to within half the building within a few hours , the fire spokesman said . Firefighters planned to remain on-site overnight . There were no reported injuries or evacuations . CNN iReporter captures flames , black smoke from bridge . If the sight of the large column of rising black smoke was n't enough , people were being told not to go outside . `` If you do n't have to go out , we advise to stay inside , '' Keller said Saturday . The National Weather Service issued a dense smoke advisory through 6 a.m. Sunday for much of Georgia 's Chatham County , including parts of the Savannah metropolitan area . This is an extension of a previous advisory that was supposed to end at 11 p.m. Visibility was expected to be at its worst through 4 a.m. or 5 a.m. , and problems could become exacerbated when fog mixes in with the smoke . `` Everyone is encouraged to stay indoors as the air quality will be hazardous . Avoid strenuous activities if you must work outdoors , '' the advisory warned . `` Motorists should be alert for sudden changes in visibilities . '' The Savannah College of Art and Design tweeted that people should avoid the River Street area , a popular spot for tourists filled with restaurants and stores . Kayvon Gerami , a CNN iReporter , said that people stopped along the Talmadge Memorial Bridge to photograph the fire . `` The black smoke started to look like a tornado , '' the 28-year-old Gerami said . `` And now it smells like burnt tires everywhere . '' Firefighters got some help from the weather . Winds were calm , according to the National Weather Service . `` Pretty much ( the smoke ) is going straight up , '' said Vern Beaver , a National Weather Service meteorologist in nearby Charleston , South Carolina . `` It does n't seem to , right now , be producing much of a restriction to visibility . '' Winds out of the north-northeast were expected to pick up and be about 8 mph , Beaver added . If they do , they 'd push whatever smoke is left offshore over the Atlantic Ocean . Authorities have n't yet determined what caused the fire . Keller said it wo n't be until Sunday or later when investigators can get into what 's left of the charred warehouse .
