Tropical Storm Otis Discussion Number 30
NWS National Hurricane Center Miami FL EP152017
800 PM PDT Mon Sep 18 2017
The cloud pattern has deteriorated significantly and the circulation
is becoming elongated. Given the lowering of Dvorak estimates
tonight, the initial intensity has been reduced to 35 kt. Dry air
and cooler waters will continue to affect the cyclone, and
additional weakening is forecast. Otis is anticipated to degenerate
into a remnant low in about 24 hours or sooner.
Since Otis is weakening and becoming a shallow system, it will be
steered southwestward by the low level-flow until dissipation.
