INVEST 92L Key Messages:
– Watches & Warnings: An Adverse Weather Alert (Yellow Level) was issued at 6:51 AM for T&T, which went into effect at 7:00 AM through 6:00 PM. Given that the center (and strongest winds) of this system is forecast to move across the Leewards, well north of T&T, tropical storm watches/warnings may be issued for those islands later today.
– Track: The track of INVEST 92L stays well north of T&T. The core of INVEST 92L is forecast to track across the Leeward Islands. Peak activity across is expected on Tuesday through early Thursday.
– Intensity: iNVEST 92’s large size, multiple low-level circulations, and struggle with dry air will inhibit any rapid development or intensification. However, a tropical storm is likely to form over the next 48 hours and 5 days respectively, due to high chances for formation from the National Hurricane Center as of 2:00 AM Tuesday.
– Rainfall: The rainfall forecast is elevated. Across Trinidad and
Tobago, between 50-100 mm of rainfall possible between Tuesday through Friday. Isolated totals in excess of 150 mm possible.
– Flooding: Street flooding and flash flooding in heavy to violent showers and thunderstorms are likely across both islands. There is a very low to low chance of riverine flooding across Trinidad.
– Landslides: There is a high risk of landslides across both islands
– Seas: Seas, mainly on Tuesday through Tuesday, forecast to be moderate to rough, with waves up to 2.5 meters, occasionally up to 3.0 meters in open waters, mainly east of Trinidad and in Tobago’s coastal waters. In sheltered areas, up to 1.0 meters and choppy.
– Winds: Gusty winds in excess of 65 KM/H are possible across T&T in the event of showers/thunderstorms. Winds of this strength will produce wind damage including downed trees, utility poles, and roof damage. Power outages possible.
