Atlantic hurricane season is headed toward its typically busiest time of year, and one disturbance could become Tropical Storm Dolly later this week.
Here are the areas we’re watching
The graphic below shows the two areas that are being monitored by the National Hurricane Center.
One is located in the central Atlantic east of Bermuda and the other is located in the eastern Atlantic.
Chances of development?
Central Atlantic (Invest 95L): This low is located a few hundred miles east-northeast of Bermuda. The system still could become a short-lived depression or storm Tuesday as it continues to drift north away from Bermuda. However, its window for development is expected to close by Wednesday.
Eastern Atlantic (Invest 96L): A tropical wave is off the coast of Africa south of the Cabo Verde Islands and could develop into a tropical depression, then possibly Tropical Storm Dolly within the next few days.

Are either of these a threat?
The central Atlantic low may enhance rain and gusty winds in parts of Newfoundland later Tuesday into early Wednesday, but then will merge with a cold front and is, therefore, no significant threat.
The eastern Atlantic system is still about 2,500 miles away from the Lesser Antilles.
There appear to be two options with this:
It could struggle with the same El Niño-enhanced wind shear and dry air other systems have fought against in recent weeks as it continues moving toward the west-northwest, arriving near the Lesser Antilles by Sunday with some increase in showers.

If it fights off this shear and dry air and develops, it’s expected to then make a northward turn next week in the Atlantic, where it could escape El Niño’s influence. Some computer guidance says this could be a tropical storm or hurricane as it gets to the subtropical Atlantic a week to ten days from now. 
While it’s too soon to be certain about what happens with this system next week, it is not an immediate concern for the mainland U.S.
Those in the Lesser Antilles should monitor the progress of this system, as with any system during hurricane season.
Tropics on the rise
We are in the ramp-up of the Atlantic hurricane season.
The escalation begins in August and continues until peak hurricane season in the second week of September.
El Niño is also ramping up, but that doesn’t guarantee that no storms will form. It just hinders their chances.
It only takes one storm to make a hurricane season impactful.
