In Atikinson's Liberation Trilogy, in the 2nd volume he details the bad weather than hit the invasion force and disrupted the invasion to a degree:
https://en.wikipedia.org/wiki/Allied_invasion_of_Sicily#Battle
Strong winds of up to 45 miles per hour (72 km/h)[46] blew the troop-carrying aircraft off course and the American force was scattered widely over south-east Sicily between Gela and Syracuse.

...

The strong wind also made matters difficult for the amphibious landings but also ensured surprise as many of the defenders had assumed that no one would attempt a landing in such poor conditions.[52]

....

More trouble was experienced from the difficult weather conditions (especially on the southern beaches) and unexpected hidden offshore sandbars than from the Coastal divisions. Some troops landed in the wrong place, in the wrong order and as much as six hours behind schedule,[57]

What if the storm had gotten worse unexpectedly and ended up scattering the invasion, as well as inflicting mass damage on the force, fleet, and air units? What happens with the invasion plan then with the fleet damaged and scatter and potentially major units wrecked, like the 82nd Airborne if caught in the storm in their transports? How rapidly could the Allies get another invasion going or would it be put off for a while?
 
Off the top of my head a month delay, tho if the problem is primarily being scattered ships then a couple weeks. Thing is rerunning the same operational plan and stratigic objective might not be the best.

In most cases the navy is going to give a abort order if at all possible. ie: the decision to postphone Op NEPTUNE & order the fleet into port for 5 June. I cant remember off the top of my head if there were any others delayed at the last minute by weather, or interrupted.

.... Some troops landed in the wrong place, in the wrong order and as much as six hours behind schedule,[57]

This sounds almost normal for a coastal landing. Getting ashore in the planned location is almost a bonus.

That's a major question, given significant damage to the fleet and invasion force, even if they were able to make good losses quickly, how badly will this disrupt plans and how long to replan and launch a different invasion? Do they still even favor Sicily? According to Atkinson the invasion was ordered in bad weather due to the prediction it would end by the time the landings happened, but this what if is that the storm gets worse than it was IOTL rather than just getting somewhat less bad.

Depends. AFAIK most of the Marine landings in the Pacific were on target.

Marines did not do the navigation. Beyond that amphibious forces in the Pacific spent more time planning/rehearsing. Hawaii was one of the most invaded atolls on the planet.

MacArthur pushed Eichelberger & Kruger into planning operations in a few weeks. A experienced staff can put a reasonable operation onto paper & get a rehearsal fairly quickly. Time require expands when material has to be brought up. That is delivery boat squadrons from somewhere else, getting air support to the appropriate bases, ect... Op Shingle went from a one page concept to L Day in 8-10 weeks. Montys group reworked the COSSAC version of OVERLORD into the January version in maybe a month. In the case of the Med in early to mid 1943 there were two Army HQ planning the next op/s while the other two were involved in execution. That is while the 7th 7 8th armies were invading Sicilyy the 5th Army, French, & other staffs were working up the next ops. The naval staffs did not have as much redundancy, but they did have multiple planning cells.
