HAZARDS AFFECTING LAND
———————-
STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water is
expected to reach the following HEIGHTS ABOVE GROUND if the peak
surge occurs at the time of high tide…
Jupiter Inlet to Bonita Beach, including Florida Keys…5 to 10 ft
Bonita Beach to Venice…3 to 5 ft
Jupiter Inlet to Sebastian Inlet…3 to 6 ft
The deepest water will occur along the immediate coast in areas of
onshore winds, where the surge will be accompanied by large and
destructive waves. Surge-related flooding depends on the relative
timing of the surge and the tidal cycle, and can vary greatly over
short distances. For information specific to your area, please see
products issued by your local National Weather Service forecast
office.
The combination of a life-threatening storm surge and large breaking
waves will raise water levels ABOVE NORMAL TIDE LEVELS by the
following amounts within the hurricane warning area near and to the
north of the center of Irma. Near the coast, the surge will be
accompanied by large and destructive waves.
Turks and Caicos Islands…15 to 20 ft
Southeastern and central Bahamas…15 to 20 ft
Northwestern Bahamas…5 to 10 ft
Northern coast of Haiti and the Gulf of Gonave…1 to 3 ft
Northern coast of Cuba in the warning area…5 to 10 ft
WIND: Hurricane conditions are occurring on the Turks and Caicos
Islands, with tropical storm and hurricane conditions ongoing in the
southeastern Bahamas. These conditions will move into the central
Bahamas later today. Hurricane conditions are expected within the
hurricane warning area along the north coast of Cuba late today and
Saturday. Hurricane conditions are expected in the northwestern
Bahamas tonight and Saturday, and in portions of southern Florida
and the Florida Keys Saturday night or early Sunday.
Hurricane conditions are possible within the watch area in Florida
by Sunday, with tropical storm conditions possible by late Saturday.
RAINFALL: Irma is expected to produce the following rain
accumulations through Tuesday night:
Northern Dominican Republic and northern Haiti…additional 2 to 4
inches.
Southern Dominican Republic and southern Haiti…additional 1 to 2
inches.
Turks and Caicos…additional 3 to 6 inches.
Southern Bahamas and northern Cuba…10 to 15 inches, isolated 20
inches.
Southern Cuba…4 to 8 inches, isolated 12 inches.
The upper Florida Keys into southeast Florida…10 to 15 inches,
isolated 20 inches.
Eastern Florida northward into coastal Georgia…8 to 12 inches,
isolated 16 inches.
Lower Florida Keys…3 to 5 inches.
Western Florida Peninsula into much of Georgia…South
Carolina…and Western North Carolina…3 to 6 inches.
In all areas this rainfall may cause life-threatening flash floods
and in some areas mudslides.
SURF: Swells generated by Irma are affecting Puerto Rico, the
Virgin Islands, the southeastern Bahamas, the Turks and Caicos
Islands, the northern coast of the Dominican Republic, and should
start affecting portions of the southeast coast of the United States
later today and tonight. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.
