Before I start the forecast discussion, I’ll preface it with this…Right now, any changes in the forecast are not going to matter all that much. Just prepare for the worst and if it’s anything less, you’re lucky. Please remember that this storm is not just a line and impacts will span the state for Florida.

The 2nd landfall is expected to be near Sanibel Island on Sunday evening. The eye of the storm is expected to move up the west coast through the evening hours, finally exiting the state Monday afternoon.

The NHC has maintained their track, which is consistent with this afternoon’s forecast models. This is in line with the midday European model and between the recent GFS and NAM model runs. It is expected to move across the Tampa area as a Category 3 hurricane.

Rainfall totals across the swath covered by Irma are expected to be in the 10-15 inch range, with your obligatory isolated higher totals, approaching 20 inches.

Points of Interest:
Tampa & Polk Co (Lakeland) – Conversely, the westerly shift in the track a lot of pressure to this area. A protracted amount of time with hurricane force winds, likely 95-105 mph. Surge also becomes an issue on the north side of Tampa Bay, and will be compounded by heavy rainfall.

Orlando – At this time, It is likely that the eye of Irma will pass west of this area. Winds are expected to be in excess of 70 mph at this time.
