Invest 93L to Become Tropical Storm Irma in the Eastern Atlantic Ocean on Wednesday

As we continue to track Harvey's devastating flooding, a new area of low pressure in the eastern Atlantic Ocean will develop into Tropical Storm Irma on Wednesday.

The National Hurricane Center (NHC) has been tracking this system as Invest 93L the last couple of days, which is a naming convention used to identify features that could form into a tropical cyclone. However, the NHC says they will initiate advisories on Tropical Storm Irma for this system on Wednesday morning.

In the near-term, future Irma will bring locally heavy rain and gusty winds to the Cabo Verde Islands through Wednesday.

Invest 93L Potential Development Area
The area of low pressure is embedded in a generally moist region of the eastern Atlantic, though dry air lurks to its north and west. In addition, it should move through a portion of the Atlantic Ocean where upper-level winds are mostly favorable for development the next few days.

After passing near the Cabo Verde Islands, future Irma will then continue to move westward along the southern periphery of a North Atlantic high-pressure system, with no immediate threat to any land areas. In fact, future Irma may not reach the longitude of the Lesser Antilles (eastern Caribbean) until the early or middle portion of next week.
It's far too early to determine if this new system will pose any threat to the Lesser Antilles and if it will eventually ever pose a threat to other locations, including the U.S.
Suffice to say, there is plenty of time to watch this system.
We are in the heart of the hurricane season, so we monitor every potential Atlantic system closely for development.
Check back with for updates on this system through the weekend ahead for the very latest.
