Marine Conditions:

The Caribbean Sea

Middle to upper level diffluent flow over the NW Caribbean is supporting scattered showers and tstms in the lee side of Cuba and adjacent waters. Moderate to fresh trade winds are in this region of convection. Similar convection is the SE Caribbean associated with a tropical wave. Otherwise, moderate to fresh winds dominate the central and eastern basin with seas from 3 to 6 ft, except the Gulf of Venezuela and Colombia adjacent waters where winds have fresh to strong speeds.

High pressure N of the area extending a ridge to the northern Caribbean will continue to support moderate to fresh winds across the central and eastern basin through today, except in the south- central Caribbean where winds will be fresh to strong. Winds in the south-central Caribbean are expected to expand in areal coverage this weekend through Tue night as two tropical waves move across the eastern and central basin. Otherwise, fresh to locally strong winds will pulse at night in the Windward Passage through Sun night.

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

There are no organized systems in the Atlantic basin at this time. While there are a few tropical waves crossing the basin, tropical development is not anticipated through at least early next week, mainly due to a broad area of Saharan dust over much of the Atlantic basin.

A non-tropical low pressure system has developed a few hundred miles northeast of Bermuda. Tropical development is not expected to occur with this feature over the next few days as it accelerates northeastward across the northern Atlantic Ocean.

Through this weekend, a broad upper-air low pressure system will stall over the southwestern Atlantic. While this area will be monitored for signs of tropical or subtropical development, computer guidance continues to suggest development will not occur as there remains limited shower and thunderstorm activity at this time.

We continue to monitor multiple tropical waves tracking from east to west across the tropical Atlantic Ocean, July 15-18, 2021. We do not expect or anticipate cyclone development thru July 18, 2021.

The Caribbean winds are coming from the NNE this morning, with only a little cloud, but there is mid level cloud coming in from various angles, some causing some rain showers down the southern coast.

Looks as if today will be mainly sunny, but ther could be the odd rain shower occasionally.

No Tropical Development Anticipated Across The Atlantic, Caribbean & Gulf Of Mexico Through This Weekend & Through Next Week

Due to the continued downward motion pulse of the Madden Julian Oscillation, no tropical development is expected across the Atlantic, Caribbean and Gulf of Mexico through this weekend and likely through next week.

We now wait for the next upward motion pulse of the Madden Julian Oscillation to arrive in the Atlantic. That still looks to occur right around either the very end of this month or during the first part of August. This upward motion pulse is then anticipated to remain in place across the Atlantic through much of the month of August. Once this occurs, I expect that tropical activity will ramp back up beginning around the very end of this month or the very beginning of August.

At this point, none of the model guidance forecasts any sort of tropical development for the next two weeks or so. Beyond this, the very long range CFS model continues to forecast an uptick in activity beginning around the first of August with this model showing at least a couple of disturbances to really watch as they head westward towards the Lesser Antilles and then the Bahamas.

Some of the latest ensemble guidance are forecasting a very troubling upper air pattern for the peak of the hurricane season - in fact, it's downright ugly!! These guidance members are showing a blocking high pressure system to set up over southeastern Canada and a setup like this is usually associated with much more frequent hurricane landfalls on the US Coastline and in the Caribbean.

So, "enjoy" the quiet that we will probably have for the next couple of weeks or so because it looks like it's going to be very, very busy in terms of tropical storm and hurricane activity for August and September. In addition, with the weather pattern that looks to be setting up, it appears that very few storms will curve out into the open Atlantic, but instead head towards land. I know I sound like a broken record with my updates regarding the peak of the hurricane season, but it looks downright ugly and dangerous in terms of hurricane landfalls this season.
