Currently, I'm doing thesis using google earth engine to calculate the days of cessation of storms to CHIRPS Daily Precipitation Image Collection. The code flow is as follows:

Conceptually, it is like this. The first date of the image collection is set as the zero day for the cessation of storms. Coming to the image of next date, it examines the values of precipitation. If the precipitation is zero, the day of cessation of storms is added up one day and still continues adding until the precipitation of coming days becomes non-zero. At that case, the day of cessation of storm starts off with zero day.
The results I've obtained is an image collection in which all the elements inside have the calculated bands with value of zero which shouldn't be like this. I would like some suggestions on this problem, please.
