Otto is forecast to become a hurricane sometime tomorrow once upper level winds start to diminish. The storm is expected to slowly move eastward, potentially making landfall late this week near Costa Rica or Nicaragua as a category one hurricane with 80 mph sustained winds.
Most of the forecast models push Otto slowing into the east coast of Nicaragua or Northern Costa Rica by the end of the week.
The rainfall will stay off shower through tomorrow, but the outer bands of Otto will send squalls into Central America Wednesday, with the wind increasing into Thursday. Based on model projections, landfall may occur Friday. Intensification is likely to hurricane status.
