By The Star Staff
Hurricane Tammy was moving away from the northern Caribbean Sunday on a northern trajectory, leaving heavy rain and flooding in its wake.
The National Hurricane Service issued a flood warning for Bayamón, Guaynabo, San Juan and Trujillo Alto on Sunday afternoon.
Doppler radar indicated heavy rain due to thunderstorms, which caused urban and small stream flooding. Up to one inch of rain had fallen. Additional rainfall amounts of up to one inch were expected in the San Juan metro area, with minor flooding.
On Sunday morning the hurricane was centered near 18.9N 62.5W or 50 nautical miles northeast of Anguilla, moving northwest at nine knots. Estimated minimum central pressure was 992 mb. Maximum sustained wind speed was 75 knots with gusts to 90 knots.
Hurricane-force winds extended outward up to 20 nautical miles, mainly north of the center. Tropical storm-force winds extended out up to 120 nautical miles in the eastern semicircle.
Seas of 12 feet or greater extended out up to 180 nautical miles, especially north of the center, where peak seas were near 25 feet.
The heaviest rains from Tammy in Puerto Rico were to continue into Sunday night, with flash and urban flooding expected along with landslides in upper elevations.
