The Cayman Islands National Weather Service issued a flood advisory for the Grand Cayman on Tuesday, 9 June.

“A tropical wave is expected near the Cayman Islands today,” the National Weather Service said when it issued the flood advisory at 11.15am.

“Due to rainy conditions, some areas across Grand Cayman may already be saturated. An additional 1.5 inches of rainfall is anticipated this afternoon into tomorrow. Heavy showers are expected along with possible thunder.”

The expected impacts include flooding of low-lying and flood-prone areas. Motorists are being encouraged to drive with caution especially during periods of heavy rainfall and to slow down when traveling through areas with standing water.

The tropical wave is also bringing fresh winds of 18 mph, gusting to 30 mph. Seas are rough, with wave heights of six to eight feet. A small craft alert is in effect.

A small craft alert means that small craft should exercise caution over open waters. Within the reef and in sheltered areas, conditions may be generally less severe, but boat operators are advised to continue to exercise discretion and good judgement, as localised choppy conditions may still develop.

The outlook issued by the National Weather Service indicates a gradual decrease in showers from Wednesday afternoon as the tropical wave moves west of the Cayman area.
