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.
