Governmental weather modification programs may well have been going on since Vietnam when back-to-back monsoons were created in the 1970s to flush out the Vietcong. The vid. below discusses government documents that have been released to the public.
So, the first condition needed for hurricanes is warmer waters in the Atlantic Ocean, which cause a number of other conditions favorable to hurricanes.
"When the waters are warmer, it tends to mean you have lower pressures. It means a more unstable atmosphere, which is conducive to hurricanes intensifying," said Phil Klotzbach, an atmospheric scientist at Colorado State University. "These thunderstorms, which are the building blocks of hurricanes, are better able to organize and get going."
Another key factor: wind shear, or the change in wind direction with height into the atmosphere, Klotzbach said.
"When you have a warm tropical Atlantic, you have reduced levels of wind shear," Klotzbach told Live Science. "When you have a lot of wind shear it basically tears apart the hurricane."
(Storms that form on different sides of the equator have different spin orientations, thanks to Earth's slight tilt on its axis, according to NASA.)
The individual ingredients for hurricanes, however, don't pop up at random; they are guided by larger weather systems.
"There are two dominant climate patterns that really control the wind and pressure patterns across the Atlantic," said Gerry Bell, the lead seasonal hurricane forecaster for NOAA's Climate Prediction Center in Washington, D.C.The first is the El Niño/La Niña cycle. During an El Niño, in which ocean water around the northwestern coast of South America becomes warner than usual, Atlantic hurricanes are suppressed, while La Niña creates more favorable conditions for hurricanes, Bell said.
The second climate pattern is the Atlantic Multidecadal Oscillation (AMO), which is, as the name implies, a trend that lasts anywhere from 25 to 40 years and is associated with warmer waters in the Atlantic and stronger African monsoons, Bell said.
"When this pattern is in its warm phase, or a warmer tropical Atlantic Ocean, we tend to see stronger hurricane patterns for decades at a time," Bell told Live Science.
A warm-phase AMO conducive to hurricanes prevailed between 1950 and 1970 and since 1995, Bell said. https://www.livescience.com/57671-hurricane-season.html
For the 2017 hurricane season, the following hurricane names could come into play in the North Atlantic, Caribbean and Gulf of Mexico, according to the WMO:
Arlene
Bret
Cindy
Don
Emily
Franklin
Gert
Harvey
Irma
Jose
Katia
Lee
Maria
Nate
Ophelia
Philippe
Rina
Sean
Tammy
Vince
Whitney
As far as predictions about tropical storms and hurricanes are concerned, I believe Katia or Lee should round out the 2017 season, but will that be the case?
What is the purpose of weather engineering programs? Some say it's for wartime advantages, some for profiteering off of tragedies, some say its to protect people from ozone issues...I don't know, but I no longer doubt that what I see occurring in the skies over where I live, the chemtrails, to be normal noxious gas residues of normal smoke escaping from jets. There is a difference between a 100 feet contrail of normal smoke from jet fuel that disperses and the abnormal criss-cross patterns of chemtrails that stretch for thousands of feet and hang in the air like a haze without dispersing.
When MDs and various research scientists worry about the health and safety of the general public, I listen to what they have to say. Aerosolized aluminum nano-sized particles sprayed in the chemtrails to engineer the weather for more rain, for cutting down on ozone exposure so the governments says using the aluminum particles that the government knows is hazardous to all life (human, animal, plant) in the USA. Criminal acts carried out unbenownst to the public at large.

An old ILP thread regarding hurricane Sandy and weather engineering was discussed.
Okay USA skeptics, what have you got?
That's a loaded question!]
