TS Zeta forms; Could be hurricane by Monday; Flood Warning for Cayman

Tropical Depression No. 28 became Tropical Storm Zeta early Sunday morning, as predicted. The tropical storm was located 177 miles SW of Grand Cayman this morning with maximum sustained winds of 40 mph and moving towards the north at 1 mph.

This is the fastest it has ever taken a hurricane season to get to 27 named storms.

The current movement of Tropical Storm Zeta takes the system further west of the Cayman Islands over the next few days. Although the tropical storm is nearly stationary, a slow generally northwestward motion is expected later today. A turn toward the west-northwest and an increase in forward speed are forecast by Monday, followed by a faster northwestward motion on Tuesday. On the forecast track, the center of Zeta will pass south of western Cuba early Monday and move near or over the northern Yucatan Peninsula or the Yucatan Channel late Monday, move into the southern Gulf of Mexico on Tuesday, and reach the central Gulf of Mexico by late Tuesday.

Pinar del Rio, Cuba is under a Tropical Storm Warning and Cozumel and Tulum to Rio Lagartos Mexico are under Hurricane Warning. Early week rains could lead to flash flooding in Cayman, Jamaica, Cuba, and South Florida.

Gradual strengthening is expected during the next 48 to 72 hours, and Zeta is forecast to become a hurricane by late Monday or early Tuesday. Tropical-storm-force winds extend outward up to 80 miles, mainly southeast of the centre.

Here's what we can expect in Cayman for both today and tomorrow, according to the Cayman Islands National Weather Service:

Widely scattered showers and isolated thunderstorms are expected to continue in association with tropical storm Zeta. Showers are expected to become heavy at times and a flood warning remains in effect.

Seas are also expected to be rough and as such, a small craft warning is in effect for the Cayman Islands. Radar images show widely scattered showers in and around the Cayman area which are moving towards the northwest.

Today, cloudy to overcast with rain and intermittent thunderstorms. Showers may become locally heavy at times leading to possible flooding of low lying areas. Temperatures will rise to the upper 80’s °F.

Winds will be south to southeast 15 to 20 knots with higher gusts in and around heavy showers. Seas will be rough with wave heights of 5 to 7 feet. A small craft warning is in effect for the Cayman Islands.

Tonight will be cloudy to overcast with rain and intermittent thunderstorms. Showers may become locally heavy at times leading to possible flooding of low lying areas. Temperatures will fall to the mid 70’s °F. Winds will be southerly 15 to 20 knots with higher gusts in and around heavy showers. Seas will be rough with wave heights of 4 to 6 feet.
