The most recent DDM updates, today August 9th, 2020 have indicated that two disturbances are being monitored in the Atlantic. One was highlighted in 7th August update by the DDM and another just recently formed not too far from the African Coast.
A disturbance (7th August update) located 865 miles to the east of the Lesser Antilles along 48W. It is moving westward at 12 mph. Although thunderstorms are increasing with the disturbance, it remains disorganized. There is a low chance of development with the disturbance over the next day or two before it encounters hostile upper level conditions. It is expected to move across the Leeward Islands or pass north of the Caribbean by Wednesday. Forecasters gave this disturbance a 10 percent chance of tropical development.
Disturbance 1 is located along 28W or approximately 2465 miles from the British Virgin Islands. It is moving to the west at 15 mph. This disturbance has become better organized. However, satellite wind data indicates that the system is not well-defined at the surface. Environmental conditions remain marginally favorable for some slow development over the next several days as this system moves westward to west-northwestward across the Tropical Atlantic. If it holds together, this system could affect the eastern Caribbean by Saturday. The risk of tropical development has increased to near 20 percent.
Forecasters have indicated that we may see an increase in the number of systems crossing the Atlantic in the latter part of August.
Persons are encouraged to monitor the systems crossing the Atlantic and complete seasonal preparations.
Persons at home and abroad are encouraged to download the DDM’s Alert app in the Apple App store or Google Play store to receive updates of any hazards affecting the Territory.
