At a Glance
- Another tropical wave has emerged from the African coast and may develop this week.
- Details on potential land impacts, if any, in the Caribbean or elsewhere are far too early to call.
Another tropical wave has emerged off the african coast this workweek, and it will be an area to watch closely for the foreseeable future as it plows westward across the Atlantic. (MORE: What is a Tropical Wave?)

The National Hurricane Center ( NHC ) said the tropical wave was located a few hundred miles west of the Cabo Verde Islands. As of Wednesday even, the NHC said that the arrangement had a 30 percentage find of developing into a tropical depression or storm in the future five days. This system has been dubbed Invest 92L, which is a appointment the NHC gives to areas of interest that have any potential to develop down the road. (MORE: What is an Invest?)

Where Is It Headed and Is It a Threat?
It ‘s far excessively early to know whether this arrangement will finally threaten any domain in a significant way. This, of course, assumes it will develop in the first place as computer exemplar calculate steering had suggested for the last few days. The atmospheric pattern this week will feature the Bermuda-Azores high becoming stronger and building westward across the Atlantic Ocean. This will steer 92L toward the west or west-northwest on the southerly periphery of the aforesaid central Atlantic high. basically, there is no escape path for this system to move northwest and then north into the central Atlantic, as occurred with Hurricane Gaston. The wave is battling batch of dry air in the easterly Atlantic and this will inhibit development, at least for the adjacent two to three days . high pressure will be locked in space across the Atlantic, forcing this modern system westbound late in the week.
however, interests in the easterly Caribbean should monitor the progress of this potential system throughout the week ahead. Any electric potential shock would not arrive in parts of the Lesser Antilles until late this weekend or early future week. ad It ‘s besides possible that it gains enough latitude while moving west-northwest in the Atlantic to avoid any brush with the Caribbean Islands. beyond that point, it ‘s besides early to speculate on any areas farther west that could be affected downstreeam next week. Always keep in beware that forecasting the track and saturation of any tropical cyclone or likely tropical cyclone can be highly challenging, even just days in improvement. ( MORE: Why Long-Range Model Forecasts in the Tropics Can’t Often Be Trusted ) Since we are talking about a situation that is a workweek or more out in time, there are many unknown variables down the road, including :
- How much dry air and wind shear could impede development.
- What the steering wind flow aloft will be near the East Coast of the U.S. and western Atlantic Ocean.
It ‘s besides a reminder that we are now in the climatologically most active prison term of the Atlantic hurricane season. (MORE: When Atlantic Season Peak Arrives) This time of year, tropical waves, besides known as african easterly waves, line up over Africa south of the Sahara Desert, and emerge into the easterly Atlantic Ocean. A fraction of these tropical waves serve as the semen for an Atlantic river basin tropical storm or hurricane each season. Regardless of whether this system becomes a threat, now is a good clock to make indisputable you have a design before a hurricane hits.
