11:20 AM | **The latest on “major” Hurricane Fiona and a look ahead to the next tropical threat** — Arcfield Weather

2 min read

Later this week, Hurricane Fiona will become increasingly influenced by an amplifying upper-level trough over the northeastern states which will bring the coolest air mass of the season so far to the Mid-Atlantic/Northeast US.  In fact, high temperatures on Friday will be confined to the 60’s in the urban areas along the I-95 corridor and there may be a stiff breeze as well. This same upper-level trough will act to “pull” Fiona back towards the northwest this weekend which may result in a direct impact on the Canadian Maritime provinces.

Next tropical threat

In addition to Hurricane Fiona, a strong tropical wave is intensifying over the south-central Atlantic.  Currently, this system is several hundred miles to the east of the Windward Islands and is likely to develop into a tropical depression over the next few days as it continues on a west-northwest track.  On this expected track, this next tropical system should travel over the warm Caribbean Sea and favorable conditions are likely to result in an intensification. Looking ahead, there are signs that this tropical system could very well become a threat to the Gulf of Mexico by the middle or latter part of next week, but it is still too early to know details such as whether it will take a track over Cuba or the Yucatan Peninsula or somewhere in between.  By the latter part of next week, high pressure ridging may build into the northeastern US/southeastern Canada which is often a red flag for tropical system to potentially “undercut” and impact the SE US/Gulf of Mexico. Residents all along the Gulf of Mexico and SE US coastlines should monitor this system over the next several days.
