Are there commentaries that suggest that the flood during the time of Noach was localised to one geographic area, as opposed to the whole Earth. In Bereishit 8:9 when the dove was sent out it says:
וְלֹא-מָצְאָה הַיּוֹנָה מָנוֹחַ לְכַף-רַגְלָהּ, וַתָּשָׁב אֵלָיו אֶל-הַתֵּבָה--כִּי-מַיִם, עַל-פְּנֵי כָל-הָאָרֶץ; וַיִּשְׁלַח יָדוֹ וַיִּקָּחֶהָ, וַיָּבֵא אֹתָהּ אֵלָיו אֶל-הַתֵּבָה.
Furthermore, the following passuk says that everything 'under all of shamayim' was covered (7:19):
וְהַמַּיִם, גָּבְרוּ מְאֹד מְאֹד--עַל-הָאָרֶץ; וַיְכֻסּוּ, כָּל-הֶהָרִים הַגְּבֹהִים, אֲשֶׁר-תַּחַת, כָּל-הַשָּׁמָיִם
However, throughout the flood story this is the only time the phrase "אֲשֶׁר-תַּחַת, כָּל-הַשָּׁמָיִם" is used. The only instance that the more all encompassing term of "עַל-פְּנֵי כָל-הָאָרֶץ" is used is when the the dove is sent out, otherwise its not used.
It seems, from the pesukim, that its not clear as to whether the whole earth was indeed covered. Since the plain meaning of the pesukim does not make it abundantly clear that the whole earth was covered do any commentaries address this issue by saying that only specific localities were affected by the flood?
