What forecasters said that day

The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Miami, FL wrote its last area forecast discussion before this small craft advisory went out at Sep 11, 1:38 AM EDT, 4 hours 4 minutes earlier.

Area forecast discussion, Sep 11, 1:38 AM EDT, 4 hours 4 minutes before

Area Forecast Discussion
National Weather Service Miami FL
138 AM EDT Mon Sep 11 2017

.AVIATION...
Hurricane Irma will continue exiting off to the north away from
South Florida during the TAF period. Conditions will slowly
improve throughout the day with MVFR ceilings eventually becoming
VFR by the afternoon. Periodic showers and gusty squalls will be
possible through most of the period. Winds will be south near or
above tropical force through the early morning, except southwest
at KAPF, before gradually weakening heading into the afternoon and
becoming southwest at all sites.

Latest thinking is that winds should subside below tropical storm
force sometime between 12z-15z. Winds will weaken further below 20
knots after 00z Tuesday.

UPDATE...
Hurricane Warning transitioned to Tropical Storm Warning for all
