TT MET SERVICE - OFFICIAL STATEMENT #3 - TWO ACTIVE TROPICAL WAVES OF INTEREST TO THE LESSER ANTILLES

TT MET SERVICE - OFFICIAL STATEMENT #3 TWO ACTIVE TROPICAL WAVES OF INTEREST TO THE LESSER ANTILLES

 The Trinidad and Tobago Meteorological Service (TTMS) has been closely monitoring two (2) active Tropical Waves, TW1 and TW2, in the Atlantic. The first wave, TW1, is located approximately 500 km east of the Lesser Antilles, centred near 13N 55W and is moving westward to west north-westward near 40 km/hr. This wave has a 10% (low) chance of development into a Tropical Depression over the next 48 hours.

 TW1 has already begun to produce locally heavy rainfall over portions of the Lesser Antilles. Current analyses suggest that on its projected track, the centre of the system is forecast to reach the Leeward Islands by tonight. The second wave, TW2, is located approximately 2100 km east of the Lesser Antilles, centred near 8.5N 40W and is moving westward to west north-westward near 35 km/hr. This wave has a 50% (medium) chance of development into a Tropical Depression over the next 48 hours.

However, it continues to show signs of additional development with a 70% (high) chance of formation over the next five (5) days. Regardless of development, this system will likely produce gusty winds and locally heavy rainfall across portions of the Lesser Antilles islands between Friday 2 nd July 2021 and Saturday 3 rd July 2021. At this time, both TW1 and TW2 pose no direct threat to Trinidad and Tobago or Grenada and its dependencies.

The TTMS will continue to closely monitor these systems and will issue an update at 6:00 pm today (30 th June 2021) or earlier if the situation warrants. As always, pay close attention to information being issued by the TTMS by visiting www.metoffice.gov.tt, downloading our mobile app (search: TT Met Office) and following us on Twitter, Facebook and Instagram.
