This satellite image taken early Saturday morning shows the broad area of low pressure spinning over the Caribbean, a couple of hundred miles to the south-southeast of Jamaica.

A broad area of low pressure in the Caribbean bears some watching for tropical development this weekend.

The low is sitting a couple hundred of miles to the south of Jamaica, over water warm enough to support an organizing tropical system.

Winds have become more favorable for development. The storm’s cloud pattern is looking more coherent compared to earlier in the week. For a look at satellite images and more discussions on potential development, visit the AccuWeather.com Hurricane Center.

Over the next couple of days, we will continue to monitor the low for potential development into a tropical depression. If the system goes on to strengthen further, it would be named Tropical Storm Arlene.

These are typical breeding areas for tropical system formation for the summer months. Note that typical breeding areas in June spans the Gulf of Mexico and the Caribbean.

A large dome of high pressure dominating over the lower Mississippi Valley will keep the system nearly stationary over the weekend.

As a result, downpours will continue to douse Haiti, the Dominican Republic, Jamaica and southeastern Cuba, whether the system organizes further or not. Localized flash flooding and mudslides can occur, especially in the higher elevations, where rainfall will be enhanced.

Any rain that falls in Cuba will be beneficial, despite the short term impacts of flooding. This is due to a severe drought situation in the island nation.

Farther out, movement of this system, whether it develops tropically or not, is still quite uncertain at this time. It could drift slowly to the northwest or move toward Hispaniola.
