A third system to potentially threaten the state of Hawaii in as many weeks is largely expected by the best models to become a tropical cyclone within the next 48 hours and track generally in the direction of within 150 miles of the islands within the next seven days. As such, we are starting a Lounge on Invest 90E at this time.

As can be seen in the visible image of 90E below from dawn today, August 19, located well east-southeast of the Hawaiian islands, 90E is a fairly large and sprawling system, unlikely to ramp up quickly at first, but it does find itself in a favorable environment for development. NHC odds for its formation into a tropical cyclone are now at 80% and going up. Assuming it does become a tropical cyclone, it could exacerbate storm damage and recovery efforts in Hawaii even without a direct hit.
