In the Tropics:

Tropical Storm Ian formed on Friday morning in the central Caribbean Sea. As of 4pm Sunday maximum sustained winds now at 50mph. By early Monday morning, Ian will turn to the northwest and become a hurricane on approach to the Cayman Islands. Rapid intensification is expected with this storm as it continues to move northwest into the northern Caribbean. Florida could be a target of then Hurricane Ian by the middle of next week.

Tropical Storm Gaston continues churning near the Azores with maximum winds of 50mph. The storm will bring heavy rain and wind to the islands while swinging around to the southwest and west while gradually weakening by Monday.

Central Tropical Atlantic:
An area of low pressure located several hundred miles west of the
Cabo Verde Islands continues to produce disorganized shower and
thunderstorm activity.  Despite the proximity of nearby dry air,
upper-level winds appear to be generally conducive and could
support some gradual development through the middle to latter
portion of this week as the system moves slowly northward.
