I agree, clean the weep holes. but, fix the problem, not the symptom, the problem is there is tree 'dirt" in window track that is plugging the weep hole. You need to vacuum or blow the entire window track clean or it could plug again the next rainfall.
My Herr windows have a plastic slider track with holes in it, I have to lift and vacuum every 6 months to keep them clean.
