As we enter winter, working natural gas in underground storage facilities in the Lower 48 states measured 3,618 billion cubic feet (Bcf) on November 5, according to our Weekly Natural Gas Storage Report released on November 10. The amount of natural gas in storage has been below its previous five-year average since mid-February of this year. Storage levels approached average in late October and early November, the time of year when inventories are typically at their highest and when natural gas begins to be withdrawn as demand rises with colder weather.
