Miami-MLS

ISAIAS ON FINAL APPROACH: Alrighty gang... this is the final call on what to expect hazards-wise. The hazards overlap. Find yourself on the map, and then see which box(es) you're in. PINK: The eyewall will affect you. Winds. gusting 80 to 100 mph, commensurate with Category 2 impacts. Power outages likely. Tree damage possible to hardwoods; palms should be mostly alright. Loose outdoor objects are tossed around. Scattered to numerous power outages. (In Pensacola, there could be a secondary burst of winds on the back side of the system out of the west-northwest... perhaps stronger than the initial side of the eye. As dry air sneaks into the circulation and erodes part of the eyewall, a "stinger" could form. While not technically a sting jet, somewhat similar processes could help make a nasty backlash of wind.) RED: Winds gusting 56 to 80 mph. Some of that is on the east side of the eyewall but outside the eyewall itself. The rest, especially in Alabama as far north as Montgomery and south of Birmingham, is from the remnant eyewall. Scattered power outages likely, and tree damage is probabkle. GREEN: This is where rainfall could overachieve, but uncertainty abounds. Confidence is high in widespread 6 to 10 inch totals, but a narrow strip of a LOT more is possible IF the feeder band swirls over the same areas for long enough. In that case, downpours would train, or move repeatedly over the same areas. BLUE: Surge. A hazardous storm surge is likely on the right side of the system, with a broad 3 to 7 feet of inundation. If you live on the immediate coastline within 7 feet of sea level, move up or inland. YELLOW: Scattered tornadoes are likely either Friday afternoon/evening or Saturday. Downpours in Isaias's feeder bands will tap into shear, or changing winds with height, associated with the overall circulation. That means some of the cells will rotate and could produce tornadoes. An isolated significant (EF2+) tornado can't be ruled out.
