URGENT - WINTER WEATHER MESSAGE
National Weather Service Houston/Galveston TX
1008 AM CST Wed Feb 17 2021
...WINTER STORM EXPECTED TO CREATE DANGEROUSLY ICY CONDITIONS
ACROSS INLAND PORTIONS OF SOUTHEAST TEXAS...
WHAT...A low pressure system will bring a period of dangerous
and potentially destructive freezing rain across the region into
the early afternoon. Ice amounts are expected to range from a
trace to a tenth of an inch along an north of the Highway 59
corridor with higher amounts in excess of one quarter inch north
of a line from Columbus to Conroe to Livingston. There is the
potential for this magnitude of ice to be very destructive,
with the potential to create additional power outages and
vegetation and tree damage. At 1000 AM, highway 105 west and FM
1486 in Montgomery County were iced over.
Temperatures will fall back below freezing tonight as colder air
spreads south in the wake of a cold front. Any residual liquid
water on roads or sidewalks will quickly refreeze. Some light
snow or sleet may also fall Thursday morning in the wake of the
front though accumulation amounts should be very light on the
order of a trace.
* WHERE...Inland areas of Southeast Texas.
* WHEN...Through Thursday morning.
* IMPACTS...Icy conditions will worsen quickly across the region
this morning. Very dangerous driving conditions from icy roads
are expected. Travel should be avoided unless absolutely
necessary. Vegetation and powerlines will become coated with
ice and as the ice accumulates to around or above one quarter
inch, will lead to breaking tree limbs and power lines. The
power outages already present in many locations could worsen.
Even though some areas may thaw out briefly, the potential for
refreeze will be high tonight with another cold front bringing
subfreezing temperatures back across the region. Any roads
that remain wet when subfreezing temperatures return will
