Sept 12 (Reuters) - The amount of natural gas flowing to

U.S. liquefied natural gas export plants was on track to slide

further on Thursday with energy companies reducing feedgas to

plants as storm Francine barreled into southeastern Louisiana,

according to data from financial firm LSEG.

Francine weakened from a Category 2 hurricane to a tropical

depression as it headed northeastward, but still packed winds of

35 miles per hour (55 km per hour) and threatened areas with

dangerous storm surges early on Thursday, the National Hurricane

Center said in an advisory.

Louisiana is home to three of the United States' seven big

operating LNG export plants.

Gas flows to U.S. LNG export plants were on track to decline

from 11.9 billion cubic feet per day (bcfd) on Wednesday to a

more than two-week low of 11.7 bcfd on Thursday, LSEG data

showed.

Total feedgas averaged about 12.7 bcfd on Tuesday and 13.4

bcfd over the prior week.

Most of that reduction was due to a drop in flows to the

2.0-bcfd Cameron LNG export plant in Louisiana from 1.9 bcfd on

Tuesday to 0.6 bcfd on Thursday. Feedgas to Cameron averaged 2.1

bcfd over the prior week.

One billion cubic feet of gas is enough to supply about 5

million homes for a day.

Officials at Cameron LNG were not immediately available for

comment on the reason for the reduction.

Cameron LNG's partners include units of U.S. energy company

Sempra Energy, Japanese corporate groups Mitsui & Co ( MITSF )

and Mitsubishi ( MSBHF ), France's TotalEnergies

and Japanese shipping line Nippon Yusen KK ( NYUKF ) (NYK Line)

, according to the Cameron website.
