411A, Jeppensen ATC chapter:
Descent below MDA(H) should not be made until:
a. visual reference has been established and can be maintained
b. the pilot has the landing threshold in sight; and
c. the required obstacle clearance can be maintained and the aircraft is in a position to carry out a landing
NOTE: The procedure does not provide protection from obstacles when the aircraft is below the OCA/H; MDA/H
All this to say that given the conditions above, this text would permit to leave the MDA even in the downwind. Remember, as stated by "boofhead", this is a visual approach procedure!
