Increasing chances of Laura and Marco developing this week


The latest projected path of the second wave has a more northern tilt, pointing the potential depression toward the northern Leeward Islands and Puerto Rico.

Forecasters are watching two fast-paced tropical waves in the Atlantic early Monday that could turn into tropical depressions later this week.

To make matters more complicated, both waves have some Saharan Dust to go through, as well as pockets of high wind shear (the red shaded areas) Both factors could disrupt development, but if the dust or shear weakens as these systems move west, then development could continue, unimpeded. Its formation chances during this time will be 50 percent.

Sebastian Daily will keep you updated as more information becomes available.

The system in the east is about 1000 miles east of the Windward Islands and is moving 15 to 20 mph.

Formation chance through 5 days.high.90 per cent. The third is still just off the coast of Africa. This system could develop into Tropical Storm Laura. Models continue to show a wide range of possible solutions, but at least some of our guidance indicates the potential for a tropical storm in the Gulf by early next week.

Over the next 5 days, both of the systems circled above has a solid chance of developing.

Formation chance through 48 hours.low.near 0 per cent.

In the near term, expect fair skies accompanied by relatively comfortable temperatures (for mid-August) in the lower 70s through Wednesday morning, followed by a mostly sunny and hot day.
