Yeah you'll be looking at 30+ mins during peak hour. I remember when works were on 34R a few years ago and some heavy rain during the early morning peak caused mayhem. Guys couldn't get visual off the RNAV, Indefinite holding, single runway ops, diversions everywhere, Int'l airline captains firing up on the radio, good times!!
Are they doing something constructive for the industry, like installing a CAT III ILS?
