SC Severe Weather Awareness Week: Thunderstorms

...SOUTH CAROLINA SEVERE WEATHER AWARENESS WEEK CONTINUES THROUGH SATURDAY...

TODAY WE WILL DISCUSS THUNDERSTORMS.

THUNDERSTORMS AFFECT RELATIVELY SMALL AREAS WHEN COMPARED TO HURRICANES AND WINTER STORMS.

A TYPICAL THUNDERSTORM IS 15 MILES IN DIAMETER AND LASTS AROUND 30 MINUTES. SOMETIMES ORGANIZED SYSTEMS OF MULTIPLE THUNDERSTORMS SUCH AS SQUALL LINES WILL PERSIST FOR MANY HOURS AND WILL IMPACT LARGER AREAS. ACROSS SOUTHEAST SOUTH CAROLINA...

THUNDERSTORMS OCCUR ON AVERAGE 50 TO 60 DAYS EACH YEAR.

THUNDERSTORMS OCCUR THROUGHOUT THE YEAR BUT ARE MOST COMMON FROM JUNE THROUGH SEPTEMBER. DURING THIS TIME OF THE YEAR...THUNDERSTORMS FREQUENTLY DEVELOP AS THE SEA BREEZE FORMS ALONG THE COAST AND PUSHES INLAND THROUGH HOT...HUMID CONDITIONS.

THUNDERSTORMS CAN ALSO MOVE OFFSHORE OR DEVELOP OVER COASTAL WATERS...POSING A DANGER TO BOATERS. REGARDLESS OF SIZE AND DURATION...

ALL THUNDERSTORMS ARE DANGEROUS BECAUSE THEY PRODUCE LIGHTNING...WHICH WE WILL DISCUSS IN MORE DETAIL TOMORROW.

THUNDERSTORMS ALSO PRODUCE OTHER HAZARDS SUCH AS STRONG WINDS...HAIL...HEAVY RAINFALL AND TORNADOES.
