DENVER -- Chipotle Mexican Grill Inc. is cautioning that factors beyond the company's control -- the weather in particular -- may prompt the removal of guacamole from its menu.

Denver-based Chipotle uses 97,000 pounds of avocados daily to make its guacamole to serve at its locations, including 22 in metro Atlanta.

The company noted higher prices of some ingredients could force the company to increase what it charges for its menu, or it could just do away with some portions of the menu.

"In the event of cost increases with respect to one or more of our raw ingredients, we may choose to temporarily suspend serving menu items, such as guacamole or one or more of our salsas, rather than paying the increased cost for the ingredients," the company says in its annual report.

(WXIA) -- With a warm weekend on the horizon, the Georgia Department of Transportation plans to perform some much-needed roadwork throughout north Georgia.

Closures and delays can be expected on a number of major roads and highways.

"Plan ahead -- I can't say it enough," GDOT District Construction Engineer Shun Pringle said in a release. "If you plan ahead, you can avoid some potentially heavy delays."

Some notable roadwork includes:

Downtown Connector
Two right lanes of I-75/85 north near University Avenue will be closed for pavement work Saturday from 9:30 a.m. to 6 p.m.

I-285
Three lanes will be closed in both directions between West Paces Ferry and Roswell roads for sign replacements. All work will take place overnight -- from 9 p.m. to 5 a.m.

ATHENS -- Posts like a link to a viral video of dancing babies, followed by a breaking news alert, followed by a photo of someone's lunch make Twitter seem random.

But a University of Georgia researcher says the social network is completely predictable. 

Itai Himelboim worked with the Pew Research Center and Social Media Foundation to track Twitter conversations. She broke down conversations into six predictable ways:

1. Polarized vs. Tight Crowd
"Polarized crowds are typically triggered by controversial political issues. Users interact with like-minded users, receive information from sources they agree with," Himelboim said. "It reminds me of high school politics- we don't talk with you, we don't listen to you, but we definitely talk about you."  

The opposite is a tight crowd, where like-minded communities form around professional topics or hobby groups and exchange specific information.
