Intercept and take down Merryweather air supply lines in Blaine County. Weaponized Dune buggies will be issued to the team and should be returned upon completion.
— Brief.

Severe Weather Patterns is a Mobile Operations mission featured in Grand Theft Auto Online as part of the Gunrunning update.


The crew is instructed to take a Dune FAV with a mounted MG provided to complete the mission (if there are more than two players, a second version with a mounted Minigun is provided as well). Agent 14 briefs the crew that Merryweather is mounting a large scale operation in Blaine County moving supplies by employing various aircraft, so he orders the crew to intercept their operations by bringing their aircraft down. They are avoiding military radar by flying close to the ground.

The crew then moves to Sandy Shores to intercept the first Cargobob, which is seen carrying a freight container. The crew proceeds to attack the aircraft while avoiding Merryweather roadblocks with Mesas and the enemy who will start throwing sticky bombs from the target helicopter's rear boarding ramp.

With the first Cargobob down, Agent 14 marks the second target above Harmony and the crew finds a second Cargobob, this time being escorted by a Buzzard Attack Chopper. Again, roadblocks will be set up and an enemy will throw sticky bombs from the target aircraft, so the crew has to take care of these threats.

After bringing the second Cargobob down, Agent 14 marks the third target in the Sandy Shores Airfield, which advises that a plane is prepping to take off. The crew moves to the airfield and intercepts a Titan, which will open the cargo ramp and let two enemies throw sticky bombs at the crew. Two Mesas will also appear to intercept the crew.

With the first Titan down, Agent 14 marks the location of a fourth target spotted near the Alamo Sea and heading to Sandy Shores. The crew moves to the location and intercept a second Titan, which is escorted by two Froggers.

With the second Titan down, Agent 14 marks the fifth and last target flying over the Los Santos Freeway. The crew moves to the location by taking care of oncoming Merryweather operatives in Mesas and roadblocks. The crew then finds the target Cargobob and proceeds to destroy it while avoiding the explosives being thrown by another enemy.

After taking out the last Cargobob, Agent 14 comments that Merryweather "took a beating" and that the "salvage team are in play". He then orders the crew to bring the Dune FAVs back to the drop off point in Cypress Flats. On the way, they may encounter some Merryweather resistance, but they are not much of a problem to the crew if they are near the drop-off location. There will be a small area with two friendly agents next to two containers and a Phantom to one side. Once the vehicle/s is/are delivered, the mission is completed.

Okay, I feel like Merryweather's capabilities are severely limited now. Well done us.
