Dealing with hurricane damaged roofs and rain coming in, often in largge quantities, getting rid of the bulk water is the first concern. Pumping, squeegeeing out, and/or vacuuming up standing water is a good start. Ripping up carpets and carpet padding and any soaked upholstery is the next step.

After that drying out the interior by 'thermal pumping' seems to work pretty well. The idea is that you crank the heat wide open, then you crank the air conditioning wide open, rinse, repeat. The idea is that raising the temperature gets the moisture into the air where the air conditioning can squeeze the air dry and drain the water away.

You can speed and intensify heating by electric heaters. And dry the air faster by running dehumidifiers. This dry air speeds evaporation. When the dry air is heated and circulated it soaks up water quite rapidly.

Getting the water out as fast as possible is good because it gives less time for mold to form and grow. Opening up the walls by removing at least one side below the water line helps.
