Dipping into rainwater of less than 40 seah: [1]
In a time of need, when one does not have a vessel and there is no kosher Mikveh available, then if one does not anticipate to receive a vessel prior to the time for shema and prayer, one should dip his hands into any available puddle of rainwater, even if it contains less than 40 seah, and then say the blessing of Al Netilas Yadayim.
