Post-Tropical Cyclone Isaias Summary

Surface observations indicate that Isaias continues to gradually
weaken over southeastern Quebec. There have been a couple of
observing sites with marine exposure along the St. Lawrence River
that have reported winds of around 35 kt within the past few
hours. Therefore, the initial intensity is set at that value for
this advisory. The post-tropical cyclone should continue to
weaken today, and the system is expected to be absorbed by a larger
extratropical low over eastern Canada on Thursday.

The cyclone has begun to decelerate and is now moving 015/24 kt.
The post-tropical cyclone should continue on a general
north-northeastward motion with an additional decrease in forward
speed over the next 12-24 hours. The updated NHC track forecast is
similar to previous advisory and is near the middle of the tightly
clustered dynamical model guidance.

This is the last NHC advisory on Isaias. Additional information
