POST-TROPICAL CYCLONE NARDA DISCUSSION NUMBER 30
NWS NATIONAL HURRICANE CENTER MIAMI FL EP142025
800 PM PDT SUN SEP 28 2025
COOLER WATERS AND DRY MID-LEVEL AIR HAVE TAKEN A SIGNIFICANT TOLL ON
NARDA. THE CYCLONE HAS BEEN DEVOID OF ORGANIZED DEEP CONVECTION FOR
SEVERAL HOURS, LEAVING MAINLY A SWIRL OF LOW- TO MID-LEVEL CLOUDS.
THE INITIAL INTENSITY IS REDUCED TO A POSSIBLY GENEROUS 30 KT. GIVEN
THE INCREASINGLY HOSTILE ENVIRONMENT, ALONG WITH STRENGTHENING
SOUTHWESTERLY SHEAR EXPECTED DURING THE NEXT DAY OR SO, REGENERATION
OF ORGANIZED CONVECTION IS NOT ANTICIPATED. AS A RESULT, THIS WILL
BE THE FINAL ADVISORY ON NARDA, WHICH HAS BECOME A POST-TROPICAL
REMNANT LOW.
THE REMNANT LOW IS FORECAST TO DRIFT NORTH-NORTHEASTWARD INTO
MONDAY, BEFORE TURNING BACK TOWARD THE NORTHWEST BY TUESDAY AS IT
BECOMES STEERED BY THE LOW-LEVEL FLOW. GLOBAL MODEL GUIDANCE
INDICATES THAT THE SYSTEM SHOULD GRADUALLY SPIN DOWN AND OPEN INTO A
TROUGH OF LOW PRESSURE WITHIN ABOUT 4 DAYS.
FOR ADDITIONAL INFORMATION ON THE REMNANT LOW, PLEASE SEE HIGH SEAS
