[Python] How to count the sum of at least two consecutive days with same the values, from...

I have an Xarray dataset with 3 dimensions (time, lon, lat) and a heat variable. The heat takes the values 1 or 0 (1 = more than 30degC, 0 = less than 30degC), and I want to calculate the number of events with at least three consecutive days with value 1 (time is in daily step)

I want to create an xarray dataset with only one-time value (one day) where each pixel will contain the number of events with at least three consecutive days with value 1.

time 155 = all July days for years 2026-2030

xarray.DataArray 'heat' time: 155, rlat: 6, rlon: 4


Do you have some ideas on how to do this?

here you can find the netcdf data EC7_heatjulZA26_30.nc

tm = 'C:/Path_to_NC/EC7_heatjulZA26_30.nc'
dmax = xr.open_dataset(tm, decode_coords="all")

da_max = dmax['tasmax']
da_max

*xarray.DataArray'tasmax'time: 155, rlat: 6, rlon: 4*


I sum (the 1 and 0) the data to one 6 x 4 raster, but I want to sum only those which are consecutively behind each other for at least 3 days.

HW=np.sum(da_max,axis = 0)
HW

array([[24, 20, 14, 11],
[26, 21, 15, 11],
[23, 23, 15, 12],
[14, 15, 14, 11],
[12, 12, 14, 11],
[14, 12, 15, 13]])
