442 PM EDT MON AUG 6 2018
...A STRONG THUNDERSTORM WITH INTENSE LIGHTNING WILL IMPACT EASTERN
LINCOLN...SOUTH CENTRAL IREDELL...NORTHWESTERN MECKLENBURG AND
NORTHEASTERN GASTON COUNTIES UNTIL 515 PM EDT...
At 442 PM EDT, Doppler radar was tracking a strong thunderstorm with
intense lightning 11 miles northwest of Huntersville, or near
Westport, moving southeast at 10 mph.
Locations to be impacted include...
Huntersville, Cornelius, Davidson, Westport, Lake Norman, Denver,
Ramsey Creek Park, Lowesville and Lucia.
In addition to intense lightning, wind gusts up to 50 mph, pea size
hail and very heavy rainfall rates up to 2 inches per hour will be
possible in these areas.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Gusty winds can blow down trees that are dead, or that have weakened
root systems. Outdoor furniture and similar items can be tossed
around if not anchored. Seek shelter indoors.
Torrential rainfall may flood areas with poor drainage, such as
ditches and underpasses. Avoid these areas and do not cross flooded
roads. Water levels of small streams may also rise rapidly. Seek
higher ground if threatened by flood waters.
Frequent lightning is occurring with this storm. If outdoors, try to
get indoors or into a hard topped vehicle. Otherwise, stay away from
open areas and isolated high objects such as trees. When indoors,
stay away from windows and doors and avoid using wired electronic
devices. Do not take a shower or bath. Try to unplug unnecessary
appliances before the storm approaches.
This storm may intensify, so be certain to monitor local radio and tv
stations, as well as local cable tv outlets for additional
information and possible warnings from the National Weather Service.
Lake Norman is in the path of this storm. Cloud to ground lightning
and gusty winds will create dangerous boating conditions.
Move to shore immediately.
