SITUATION OVERVIEW  
------------------  
 
TROPICAL STORM IRMA IS MOVING OVER NORTHERN FLORIDA. BREEZY  
CONDITIONS ARE POSSIBLE THROUGH THE DAY, PARTICULARLY OVER THE WATERS  
IN AND AROUND SOUTH FLORIDA, INCLUDING LAKE OKEECHOBEE.  
 
INTERESTS IN SOUTH FLORIDA NEED TO REMAIN CAUTIOUS AFTER THE STORM.  
STAY AWAY FROM EVACUATED AREAS AND OFF THE ROADS UNTIL IT IS SAFE TO  
MOVE AROUND.  
 
POTENTIAL IMPACTS  
-----------------  
 
* SURGE:  
FLOODING OF STREETS ON BARRIER ISLANDS AND NEAR THE INTRACOASTAL  
WATERWAY COULD CAUSE LOCAL STREET CLOSURES.  
 
* OTHER COASTAL HAZARDS:  
A HIGH RISK OF RIP CURRENTS WILL REMAIN ALONG THE BEACHES OF SOUTH  
FLORIDA.  
 
PRECAUTIONARY/PREPAREDNESS ACTIONS  
----------------------------------  
 
* EVACUATIONS:  
DO NOT RETURN TO EVACUATED AREAS UNTIL IT IS SAFE. LISTEN FOR THE ALL-  
CLEAR SIGNAL FROM LOCAL AUTHORITIES.  
 
* OTHER PREPAREDNESS INFORMATION:  
BE A GOOD NEIGHBOR AND CHECK ON THOSE LIVING NEXT TO YOU.  
 
THOSE WHO RODE OUT THE STORM AWAY FROM THEIR HOME OR BUSINESS ARE  
LIKELY ANXIOUS TO RETURN. HOWEVER, ALLOW SOME TIME FOR WORK CREWS TO  
MAKE A CLEAR PATH FOR EMERGENCY VEHICLES. DOWNED POWER LINES AND  
TREES MAY BE BLOCKING ROADS AND FLOOD WATERS MAY HAVE WASHED OUT OR  
OVERSPREAD SECTIONS OF KEY TRAVEL ROUTES. TRAFFIC LIGHTS MAY ALSO BE  
OUT OF SERVICE.  
 
DO NOT ATTEMPT TO RETURN TO EVACUATED AREAS UNTIL LOCAL AUTHORITIES  
GIVE THE ALL-CLEAR SIGNAL.  
 
DO NOT GO SIGHTSEEING WITHIN IMPACTED COMMUNITIES SIMPLY TO OBSERVE  
STORM DAMAGE. SIGHTSEERS CAN INTERFERE WITH THE TIMELINESS OF  
RESCUERS AND FIRST RESPONDERS TO NEEDLESSLY JEOPARDIZE LIVES.  
 
WHEN CLEARING OUT FALLEN TREES, BE CAREFUL WITH CHAIN SAWS AND AXES.  
ALWAYS WEAR PROTECTIVE GEAR AND KEEP OTHERS AT A SAFE DISTANCE. USE  
THESE TOOLS ACCORDING TO OPERATING MANUALS AND SAFETY INSTRUCTION.  
LEANING TREES AND THOSE WHICH HAVE FALLEN ON ROOF TOPS CAN BE  
ESPECIALLY CHALLENGING. IF YOU ARE NOT IN GOOD HEALTH OR UNSURE ABOUT  
WHAT YOU ARE DOING, HAVE SOMEONE ELSE WITH TREE CUTTING EXPERIENCE DO  
THE JOB. NEVER CUT TREES WITHOUT A PARTNER.  
 
IF USING A GENERATOR, AVOID CARBON MONOXIDE POISONING BY FOLLOWING  
INSTRUCTIONS BY THE MANUFACTURER. MAKE SURE THAT THE GENERATOR IS RUN  
IN A WELL VENTILATED SPACE.  
 
PROBLEMS WITH SEWER BACKUPS CAN FURTHER CONTAMINATE STANDING FLOOD  
WATERS. KEEP CHILDREN AWAY. ALSO, LISTEN FOR BOIL WATER ALERTS  
RELATIVE TO COMMUNITIES WHOSE TAP WATER MAY HAVE BECOME NON-POTABLE.  
 
DO NOT WADE THROUGH FLOOD WATERS. DANGEROUS WILDLIFE, CONTAMINANTS,  
AND ACTIVE POWER LINES ARE ALL POTENTIAL THREATS.
