-(id)init method-app crashes - ios

Question

I have used Crashlytics to catch errors in my application. Sometimes app is crashing and Crashlytics says that the error is in following code block.I have declared all variables in .h file.
-(id)init
{
if ( self = [super init] ) {
_currentTemperature=#"";
_currentHumidity=#"";
_currentWindSpeed=#"";
_currentStatus=#"";
self.weeklyMinTemperature=[[NSMutableArray alloc]init];
self.weeklyMaxTemperature=[[NSMutableArray alloc]init];
self.weeklyHumidity=[[NSMutableArray alloc]init];
self.hourlySummary=[[NSMutableArray alloc]init];
}
return self;
}
The error log is like following.
EXC_BAD_ACCESS_KERN_INVALID ADDRESS
