July 8 (Reuters) - Airlines in the United States

canceled more than 1,300 flights on Monday as Hurricane Beryl

intensified and made landfall in Texas.

A total of 1,331 flights were canceled and 505 flights were

delayed as of 6.06 a.m. ET, according to flight tracking website

FlightAware.

United Airlines led the list with 406 flights,

followed by Southwest Airlines ( LUV ) at 268.

Both United and Southwest ( LUV ) issued travel advisories citing

Hurricane Beryl impacting flights in airports including Austin,

Corpus Christi, Harlingen and Houston among others in the

region.

Beryl, which left a trail of destruction this week in the

Caribbean, killing at least 11 people, was now a category 1

hurricane and may strengthen into a category 2 by landfall on

Monday, the U.S. National Hurricane Center said.

The largest ports in Texas also closed operations and vessel

traffic on Sunday after Beryl intensified.

The Federal Aviation Administration on Friday warned of

thunderstorms impacting travel across the country.
