I have sliding glass windows on Aluminium tracks and when it rains heavily (especially when it is windy) the rain water comes in on the window sill & wets the wall underneath.
The water seems to be filling the window tracks & then entering. Any thoughts on how to fix this?
Edit:
I am adding a photo of the window tracks. The weep holes seem present and unblocked? There's a trio of aligned holes on the track rails. This is a three panel horizontal sliding window.
For approx. a 6 ft horizontal span of window there seem to be three sets of holes laterally. Do I need more holes? Larger holes?
What else could be the problem? The water influx seems to only happen when it rains heavily and on windy days. Being in a subtropical climate the thunderstorms can be quite severe.

The lower track of a window frame normally is supposed to have small holes at its lower edge toward the outside that allows water in the track to drain out. These are commonly called weep holes.
It is a common problem that over years dirt can collect on the bottom of the track and clog up these holes so the track will no longer drain. Look to see if yours are clogged and clean if necessary.
