Plenty of tropical shenanigans going on around the world this week

While there are no tropical cyclones expected to make landfall through at least Thursday, there is plenty to talk about.

Super Typhoon Trami 9/24

We will start with the biggest dog of the pack, Super Typhoon Trami, which has about as perfect of an eye as I have ever seen.

The storm is currently spinning over the open west Pacific Ocean and will threaten areas from Taiwan to Japan later this weekend and this weekend.

Trami is expected to remain a super typhoon the next several days, so take a look at more satellite images and loops of this powerful storm if you get a chance.

Leslie 9/24

Shifting our sights half way around the world we will focus on Subtropical Storm Leslie. While Leslie is no threat land over the next week at least, the storm could get pulled northward and then strengthen over the northern Atlantic ocean later this week into next week.

While it would not be a true tropical cyclone, it could be a threat to bring powerful winds and rain to the Azores next week and anyone in western Europe should keep an eye on this storm.

S PAC 9/24

I am also watching for potential development in the South Pacific Ocean this week and that could result in the first named tropical cyclone of the season for the basin.

Regard of development, areas from the Solomon Islands to Vanautu and New Caledonia should monitor this system closely this week.

Europe 9/24

Model showing potent storm developing between Greece and Italy later this week

A cold-core cut-off low will drop southward from eastern Europe into the eastern Mediterranean Sea later this week and could sit over the warm waters for several days and intensify.

I am not a big fan of the term "medicane" but a potent storm could develop and bring the risk for heavy rainfall and some locally strong winds to Greece or Italy late this week or this weekend.

A similar storm caused deadly flooding in Tunisia over the weekend when it dropped southward from the western Mediterranean Sea into northern Africa.

Mexico 9/24

Finally, we shift our gears to the eastern Pacific Ocean where multiple tropical threats may form in the next 5-7 days.

Initially these tropical concerns are expected to be off the coast of Mexico; however, as the GFS shows in the above image there is the concern for one or more tropical cyclones to track northward and threat Northwest Mexico and the southwest United States.

This particular run of the GFS model may be a bit overdone but it shows a particularly strong tropical system still maintaining a circulation as it tracks into southern California and a second storm track northward behind it into Baja California.
