In the hours before
Special weather statement, Feb 15, 2:28 PM CST, 3 hours 5 minutes before
MSZALL-160000- SPECIAL WEATHER STATEMENT NATIONAL WEATHER SERVICE JACKSON MS 215 PM CST MON FEB 15 1993 ...THUNDERSTORMS POISED TO THE WEST...SOME SEVERE FOR TONIGHT... STRONG TO SEVERE THUNDERSTORMS HAVE ERUPTED FROM NORTHWEST LOUISIANA BACK INTO CENTRAL TEXAS THIS AFTERNOON. THESE STORMS ARE MARCHING EASTWARD AT BETWEEN 40 AND 50 MPH MEANING THAT THEY COULD REACH THE MISSISSIPPI RIVER BETWEEN 4 AND 6 PM CST. A TORNADO WATCH IS ALSO IN EFFECT FOR MOST OF THE NORTHWEST HALF OF LOUISIANA AT THIS TIME. A DEEPENING LOW PRESSURE CENTER NEAR WACO, TX WILL ACCELERATE NORTHEAST REACHING NEAR MEMPHIS BY MIDNIGHT. STRONG SOUTHERLY WINDS GUSTING UP TO 35 OR 40 MPH ARE LIKELY TO IMPACT THE WESTERN HALF OF MISSISSIPPI SHORTLY AND A WIND ADVISORY REMAINS IN EFFECT FOR THOSE AREAS. INCREASING WARM MOIST AIR FROM THE GULF OF MEXICO WILL FUEL THE THUNDER- STORMS AS THEY RACE ACROSS THE MAGNOLIA STATE TONIGHT. < RESIDENTS OF MAINLY CENTRAL AND SOUTH MISSISSIPPI SHOULD KEEP TUNED TO THE LATEST WEATHER INFORMATION THROUGH TONIGHT. CHECK YOUR SAFETY PLANS AND BE READY TO SEEK SHELTER IN A STURDY BUILDING ON THE LOWEST FLOOR AWAY FROM WINDOWS. THIS IS BECOMING A DANGEROUS WEATHER SITUATION AND YOUR RESPONSE TO APPROACHING SEVERE STORMS COULD SAVE YOUR LIFE... SECONDS CAN BE THE DIFFERENCE.
