Areas affected...coastal plain of South Carolina and adjacent North
Carolina

Concerning...Tornado Watch 662...

Valid 301814Z - 302015Z

The severe weather threat for Tornado Watch 662 continues.

SUMMARY...An increase in showers and thunderstorms with embedded
rotation capable of producing tornadoes still appears possible
across the South Carolina coastal plain through 4-6 PM EDT.

DISCUSSION...The broadening/weakening circulation center of Idalia
is gradually accelerating across and northeast of the Waycross GA
vicinity,and will approach the Savannah GA vicinity through 20-21Z.=20
While a lead convective band has pivoted well ahead of it, across
and east of the Charleston SC area, scattered discrete convective
cells continue to develop in the wake of this band, offshore into
coastal areas near and southwest of Charleston. Clockwise-curved
low-level hodographs have been enlarging along South Carolina
coastal areas in advance of Idalia, where a tropical moist
boundary-layer remains potentially unstable in advance of the
mid-level warm core. And there still appears a window of
opportunity for the environment to become conducive to cells with
strengthening low-level mesocyclones posing increasing potential to
produce tornadoes during the next few hours.
