August 28, 201610 yr Author Where did the name Invest 99L come from? Invest 99L means the following. Invest a designated area of disturbed weather that is being monitored for tropical cyclone development. The numbers the National Hurricane Center uses is from 90-99 they just repeat once they reach 99. This is so they can track multiple areas. The L means the area is in the Atlantic Ocean. If they use E that means it is in the Pacific Ocean.

August 30, 201610 yr Author Some areas of Florida could get upwards to 10" of rain by Friday afternoon. Those areas are shaded in brown. This NAM outlook goes just to 2 pm EDT Friday afternoon.
August 30, 201610 yr Author Just finished reading the forecast discussion for Tropical Depression Nine. This system has moved more westerly than predicted. This could mean more strengthening the previous thought. A Tropical Storm or Hurricane Watch maybe issued for parts of the Florida Coast later today.
August 30, 201610 yr As of 11 AM, the projections look to be moving more northward as well. The worse storm surge projections are around Homassa, north of the Bay Area. I worry more about storm surge and wind than I do rain.
August 30, 201610 yr Author I will be starting a new thread since a Hurricane Watch has been issued for parts of Fla Gulf Coast.
