The forecast track of tropical storm Tammy remains relatively unchanged with the center still projected to pass north of the island this afternoon. Additionally, potential impacts expected for Barbados from Tropical Storm Tammy remain the same from the previous updates.
At 8 a.m., the centre of Tropical Storm Tammy was located near 14.0N 58.4W, or approximately 90 miles (150KM) east northeast of Barbados.
Maximum sustained winds have increased to near 65mph (100km/h). Tammy continues to move slowly westnorthwestward at 7mph (11km/h) with a minimum central pressure of 1000 MB.
A tropical storm watch remains in effect for Barbados.
A tropical storm watch is issued when sustained winds of 34 to 63 knots (39 to 73 mph; 63 to 118kmh) associated with a tropical storm are possible in the watch area within the next 48 hours.
Marine conditions have deteriorated overnight with moderate to rough swells of 2.5 m to 3.5 m (8ft to 11ft) in open water. As a result, a small craft warning remains in effect until 6 p.m. today and the high surf advisory also remains.
Some occasional light to moderate showers occurred overnight as feeder bands moved across the island and this is expected to persist during the day with shower activity likely to increase this afternoon and into tonight. Occasional winds gusting to storm force in moderate to heavy showers associated with feeder bands are possible. The BMS is forecasting rainfall accumulations of around one to three inches with isolated higher amounts during the passage of Tammy.
Any intensification of feeder bands to the southeast of the system can result in the watch being upgraded to a warning at short notice.
The public is urged to continue to monitor the progress of this system through updates issued by the Barbados Meteorological Services and follow the guidance and recommendations provided by the Department of Emergency Management.
The next advisory will be issued at 11 a.m. (PR/SAT)
