3. PUBLIC WEATHER IMPACTS AND WARNINGS SUMMARY
NUMEROUS NOVA SCOTIA LOCATIONS HAVE REPORTED ABOUT 50 MM OF RAIN
UP TO FORECAST TIME AND WERE STILL RAINING. IT IS LIKELY THAT TOTAL 
ACCUMMULATIONS IN SOME PLACES COULD BE 60-70 MM. STORM FORCE WIND 
GUSTS BLEW ALONG THE ATLANTIC COAST OF NOVA SCOTIA THURSDAY WITH THE 
HIGHEST VALUES OF 119 KM/H BEING REPORTED FROM BACCARO POINT.

NUMEROUS PUBLIC REPORTS FROM THE HALIFAX REGIONAL MUNICIPALITY 
INDICATE MANY TREE BRANCHES AND POWER LINES DOWN AND EVEN A FEW 
TREES. THIS WAS LIKELY DUE TO TREES BEING IN FULL LEAF AND THE GROUND 
BEING WET.

THE ATLANTIC STORM PREDICTION CENTRE IS MAINTAINING WIND AND HEAVY 
RAIN WARNINGS FOR PORTIONS OF NOVA SCOTIA AND WIND WARNINGS FOR 
PORTIONS OF SOUTHERN NEWFOUNDLAND. DETAILS CAN BE FOUND IN THE 
BULLETINS ISSUED BY THE ATLANTIC STORM PREDICTION CENTRE.

4. MARINE WEATHER IMPACTS AND WARNINGS SUMMARY
THE ATLANTIC STORM PREDICTION CENTRE IS MAINTAINING STORM AND GALE 
WARNINGS FOR MANY MARITIME AND NEWFOUNDLAND MARINE AREAS.
DETAILS CAN BE FOUND IN THE BULLETINS ISSUED BY THE ATLANTIC STORM 
PREDICTION CENTRE.

5. TECHNICAL DISCUSSION

A. ANALYSIS
AS MENTIONED IN THE PREVIOUS BULLETIN... THIS STORM IS AN INTENSE 
EXTRATROPICAL STORM THAT GOT JUICED BY THE TROPICAL INGREDIENTS
FROM ALBERTO LAST NIGHT. HOWEVER FOR CONTINUITY IN COMMUNICATION WE 
ARE CALLING IT POST-TROPICAL ALBERTO. IT IS MOST LIKELY THAT SOME 
CYCLOGENESIS WOULD HAVE OCCURRED ANYWAY HOWEVER THE INTENSITY AND 
DEPTH HAVE CLEARLY BEEN INFLUENCED BY THE TROPICAL SYSTEM.

PT ALBERTO MAINTAINED INTENSITY THURSDAY AFTERNOON WITH A CENTRAL 
PRESSURE AROUND 970 MB AND STORM FORCE WINDS REPORTED FROM ALL 
QUADRANTS.

THE DRY AIR CONTINUED WRAPPING AROUND THE STORM AS IT WOUND UP 
THURSDAY AFTERNOON WITH SABLE ISLAND COMING UNDER CLEAR SKIES WHILE 
EXPERIENCING SOUTHERLY GALES. NEARING SUNDOWN THE VISUAL IMAGERY 
SHOWED ONE OF THE BEST LOOKING COMMA STRUCTURES LIKELY TO BE SEEN
IN THE MONTH OF JUNE.

B. PROGNOSTIC
MODELS CONTINUE SHOWING A LOT OF CONSISTENCY OVER THE NEXT 24 HOURS 
AND THERE IS LITTLE REASON TO CHANGE OUR PREVIOUS TRACK. NONE OF
THE MODELS INITAILIZED THE STORM DEEP ENOUGH SO WE HAVE FOLLOWED
THE BASIC TRENDS FOR THE CENTRAL PRESSURE BUT CALIBRATED TO THE REAL 
INTENSITY OF THE STORM.

C. PUBLIC WEATHER
NONE.

D. MARINE WEATHER
NONE.
