==DISCUSSION==

A PROLONGED PERIOD OF HEAVY RAIN IS EXPECTED. 

LOCATIONS: CENTRAL AND NORTHERN NOVA SCOTIA. 

TOTAL RAINFALL: 40 TO 60 MM, WITH LOCAL AMOUNTS NEAR 100 MM 
POSSIBLE. 

TIME SPAN: TODAY AND TONIGHT. 

REMARKS: A SLOW-MOVING WEATHER SYSTEM WILL SUPPORT A PROLONGED 
PERIOD OF RAINFALL. THE HUMID NATURE OF THIS SYSTEM COULD GIVE 
EMBEDDED THUNDERSTORMS WITH RAINFALL RATES IN EXCESS OF 15 MM PER 
HOUR. SOME OF THESE BANDS COULD PERSIST OVER SOME AREAS, LEADING TO 
LOCALLY HIGHER AMOUNTS. 

SIMILAR STORMS IN THE PAST HAVE CAUSED: 
- LOCALIZED FLOODING, ESPECIALLY IN AREAS WITH POOR DRAINAGE 
- ROAD SHOULDER EROSION AND WASHOUTS

WATER WILL LIKELY POOL ON ROADS AND IN LOW-LYING AREAS. 

RAINFALL WARNINGS ARE ISSUED WHEN SIGNIFICANT IMPACTS ARE EXPECTED 
DUE TO RAINFALL AMOUNTS. 

PLEASE CONTINUE TO MONITOR ALERTS AND FORECASTS ISSUED BY 
ENVIRONMENT CANADA. TO REPORT SEVERE WEATHER, SEND AN EMAIL TO 
NSSTORM(AT)EC.GC.CA OR POST REPORTS ON SOCIAL MEDIA USING
