ATLANTIC BASIN

The weak area of low pressure the National Hurricane Center gave only a 10 percent chance of developing Sunday night quickly found its footing Monday morning, defying odds and spinning up into the second Tropical Depression of the season. This might be as strong as the system ever gets, as the environment ahead is nothing short of a minefield, littered with dry air and unfavorable winds.

Tropical Depression Two has been attached to the monsoon trough, a sort of umbilical cord of spin and rich(er) tropical moisture. It's now beginning to pull away from this area and will soon find itself on far less friendly turf. Recent satellite pictures indicate that not only has the circulation not intensified but it may have become less defined than earlier today.
The system is racing toward the west under the influence of strong high pressure anchored to its north. Whatever remains of the depression will be approaching the Lesser Antilles by Thursday and regardless could bring some much needed rainfall to the eastern Caribbean islands and Puerto Rico into the weekend.
It's worth noting that the official forecast calls for the circulation to spin down and dissipate before reaching the Caribbean Sea.

TYPHOON MATMO

The eye of Typhoon Matmo is closing in on Taiwan. Radar pictures show the center of Matmo only about 100 miles southeast of the main island, with winds already gusting to 115 mph at Lanyu Township on Orchid Island off the southeastern coast.
Maximum sustained winds are estimated at 90 mph and the center of Matmo will be moving across Taiwan during the morning hours eastern time (evening hours local). The typhoon should weaken some as it passes over the mountains of Taiwan and briefly reemerge over the Taiwan Strait before second landfall over mainland China on Wednesday.

ELSEWHERE

Another system is forming in the western Pacific about 1,000 miles east of the Philippines. Slow development is possible as it moves west-northwestward over the next few days.
Two areas are being monitored for development in the eastern Pacific. Showers have increased near the westernmost disturbance (Invest 91-E) but it is moving farther out to sea. Weather models are forecasting another area of low pressure to form well south of Mexico later this week, but it too should pose no threat to land.
