Ioke is now expected to transition into a very powerful 965mb extra-tropical cyclone and impact the Aleutians and southern Alaska. NWS Anchorage: MODEL UNCERTAINTY EXISTS WITH NEXT STORM TO IMPACT THE ALEUTIAN CHAIN WED/THU. THE GFS IS BY FAR THE FASTEST OF SOLUTIONS WHERE ECMWF IS MUCH SLOWER BEYOND WED NIGHT (07/12Z). PRESSURES APPEAR TO BE WITHIN THE BALLPARK. SINCE THIS SYSTEM HAS TROPICAL ORIGINS...AM FAIRLY CONFIDENT THIS WILL BE A SIGNIFICANT STORM...BUT POSITIONING WILL CONTINUE TO BE A PROBLEM. FOR NOW WILL NUDGE WINDS UP IN EXTENDED FORECAST PERIODS AND WATCH SYSTEM AS IT EVOLVES. |
