NWS STORM PREDICTION CENTER NORMAN OK
0736 PM CDT WED OCT 21 2026
AREAS AFFECTED...FAR SOUTHERN CALIFORNIA COAST
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 220036Z - 220230Z
PROBABILITY OF WATCH ISSUANCE...5 PERCENT
SUMMARY...CONVECTION APPROACHING THE COAST MAY POSE A BRIEF THREAT
OF A WEAK TORNADO AND DAMAGING WIND GUST OVER THE NEXT FEW HOURS. A
WATCH IS UNLIKELY GIVEN THE MARGINAL AND ISOLATED NATURE OF THE
THREAT.
DISCUSSION...CONVECTION HAS DEEPENED AND STRENGTHENED ALONG A
CONVERGENCE BAND OFF THE FAR SOUTHERN CALIFORNIA COAST AND WILL MOVE
ONSHORE IN THE NEXT COUPLE OF HOURS. WHILE THE CONVECTION CURRENTLY
LACKS LIGHTNING, THERE HAS BEEN A HISTORY OF ROTATION OFFSHORE.
DESPITE THE SHALLOW AND MEAGER INSTABILITY, THERE IS SUFFICIENT
DEEP-LAYER AND LOW-LEVEL SHEAR TO SUPPORT STORM ORGANIZATION AND
ROTATION. AS SUCH, THE POTENTIAL FOR A WEAK TORNADO AND A STRONG
WIND GUST WILL EXIST AS THIS BAND MOVES ONSHORE.
