The company issued an advisory on Sunday that is effective through Tuesday as frigid weather is expected to sweep back into the region beginning that day. The CIG pipeline system delivers gas from the U.S. Rocky Mountains and Anadarko Basin (located across the Texas Panhandle, Oklahoma, western Kansas and southeast Colorado) to customers in Colorado and Wyoming and indirectly to the U.S. Midwest, Southwest, California and the Pacific Northwest, it said on its website. "We're asking shippers and producers to take into account that weather conditions may change and forecasts for cold weather could impact the CIG system in coming days," said Richard Wheatley, a spokesman for El Paso in Houston. Frigid weather is expected in Texas and New Mexico again on Tuesday, said Tom Downs, a meteorologist with Weather 2000 in New York. "In West Texas especially it's going to be another shock to the system, but not as cold as last week," he said. "An Arctic front is expected sometime tomorrow afternoon into evening." In the next 48 hours there is a chance New Mexico will see 4 or more inches of snow from Albuquerque southward, Downs added. Last Thursday, the governor of New Mexico declared a state of emergency as gas supplies were cut off to thousands of residents. [ID:nN03173614]. A substantial amount of natural gas production is still offline. Total U.S. marketed gas production was off about 6 percent on Monday, down from around 9 percent last Friday, said Matt Marshall, senior energy analyst with Bentek Energy in Evergreen, Colorado. That number was estimated lower last week at about 5 percent of U.S. demand. "One hypothesis is producers see more cold weather coming and they are thinking why go reset everything when you have another bout of cold weather coming," said Marshall. The Anadarko Basin is still off about 450 million cubic feet a day, Marshall estimated. The Fort Worth Basin in Texas hasn't seen any improvement, and is still off at least 700 mmcfd, he added.reuters.com
