Two Lows to Watch

The National Hurricane Center (NHC) is monitoring two lows on Sunday for possible development. Both are East of the Lesser Antilles and could turn into tropical depressions down the road .

Invest 93L

A low pressure sitting in the middle of the Atlantic Ocean, is now known as Invest93L. Invest for an area NHC would like to INVEST-igate further, 93 is a tracking number, & "L" stands for the Atlantic Basin.

Top Winds: Nearly 30 mph

Located: 14.1°N 42.7°W
Minimum Central Pressure: 1010 mb, 29.82"

As of Sunday afternoon, its chances for development were at 40 % over a period of 5 days.  NHC says showers and storms have become more active with this low and that atmospheric conditions may allow it to organize into a depression / storm later in the week.

Where may it go?

Forecast track models in the infancy of a system are merely educated guesses. They perform much better once there is a closed center of circulation. Until then, they are just a guide for us in order to monitor.

The models are so widespread at this point, some take it as far south as the Caribbean Sea and others as far north as the Western Atlantic.  All we can do at this moment is watch. 

Invest 94L

This one is a little closer to the Lesser Antilles and could be more of an issue there. It's presently a few hundred miles east of the Windward Islands, which is the Southern end of the Lesser Antilles, moving northwestward at 10 - 15 mph. It has a 50% chance for growth.

Top Winds: Nearly 30 mph

Located: 11.9°N 52.9°W
Minimum Central Pressure: 1009 mb, 29.79" 

NHC says that here too the atmospheric conditions may allow it to develop into a depression / storm in the next few days. Even if it doesn't develop, the low may be near the Virgin Islands, Puerto Rico as well as the rest of the Leeward Islands, by Late Monday / Early Tuesday with some pockets of heavy rain. Afterwards it should make its way into the Caribbean Sea, where it may track towards the Greater Antilles. Again, even without organization, it could pack some gusty winds and heavy rain. 

Where may it go?

If nothing were to change with the steering winds, the low could potentially track over many islands. This could help change its course and intensity if it were to develop. Too many uncertainties to determine a precise path until it organizes.   

Saharan Dust

Saharan Dust is surrounding both features at the moment. It could help keep them in check. All of the oranges and reds in this image represent different intensities of dust. The red = very heavy concentrations. These dust clouds emerge from the Saharan Desert and keep the air relatively dry starving tropical systems of much needed moisture to develop.

Bottom Line

It is hurricane season and we are roughly a month away from peak activity. We should all pay close attention as many things can happen in the next few days.  

I, along with the entire 7Weather team, will keep you updated with the very latest.
