Over the next couple of days, Tropical Storm Beta is expected to gradually
intensify as it drifts northwest across the northern Gulf of Mexico. The
storm is expected to reach hurricane-force strength as it approaches the
Texas Coastal Bend on Monday. Life-threatening storm surge and hurricane
force winds are possible along portions of the northwestern Gulf Coast,
with tropical storm conditions expected by late in the weekend. Storm
Surge and Hurricane watches and Tropical Storm warnings are in effect.
Residents in these areas should ensure that their hurricane plan is in
place and follow advice given by local officials. Due to its slow motion,
Beta has the potential to produce long-duration, heavy rains -- resulting
in widespread significant flooding along the western Gulf Coast.
Elsewhere, dry conditions are expected across much of the remainder of the
U.S. into early next week. Strong high pressure will continue to support
dry conditions and below-normal temperatures across much of the eastern
U.S. through the remainder of the weekend. Frost and freeze warnings are
in effect for Saturday night and Sunday morning from portions of the Great
Lakes and Northeast to the central Appalachians. From southern New England
to the Southeast, daytime temperatures along the East Coast on Sunday are
expected to remain several degrees below normal in most places.
A frontal system is expected to bring beneficial moisture and cooler
temperatures as it moves across the northern Rockies into the Plains on
Saturday. However, gusty winds and dry conditions ahead of the system
have resulted in another day of Red Flag warnings for portions of the High
Plains and Great Basin. This system is not expected to produce a lot of
precipitation as it moves across the northern Plains and Upper Midwest on
Sunday. Above normal temperatures are forecast to continue across the
northern and central Plains on Sunday, before extending into the Upper
Midwest on Monday.
