Doors and Windows - No weep holes?

After 10 inches of rain in 13 hours (thanks, Ernesto), I have water in the tracks of my windows. There's also green mold, so this has been going on for a while. There doesn't appear to be a leak into the house yet.

I'm not a window expert, but the windows are white, possible vinyl? It's a large window that opens side to side. Both glass parts move side to side as well as the screen.

There are two tracks where water stood. One is exposed when the window is opened, the other when the screen is opened. I poked around and found no holes or slits or anything.

I noticed this after dark, so I'll look at the outside in the morning.

Can I drill my own weep holes?

Thanks,

You can drill weep holes. A 1/8" drill bit should do the job. Keep an eye on weep holes when you clean your windows to make sure they do not become clogged.
