The Great Tribulation begins with the signing of a covenant between the AntiChrist and Israel. This has not yet occurred.
IMHO, the fires in CA have not been caused by lightning nor ‘dry lightning”, but a much more plausible explanation is that many groups of masonic related orders believe they can advance their worldly agendas by setting the fires, then appealing to the fire protection agencies as false objects of hope, and to justify larger tax appropriations for their own worldly constructs.
If this isn’t the case, the masonic groups might simply appeal to ‘lightning’ and other natural causes where lighting is rarely if ever seen nor thunder heard, as the cause of calamity.
IMHO, arson on a grander scale is far more consistent in a social public which condones Wicca, witchcraft, and other worldly counterfeits to what God has provided.
The Tribulation will begin about 42 months after the signing of that covenant, and will last about 42 months. Then the catching away of the saints. Then the Wrath of God (including the Woes) on those who are not caught away, who refuse to believe in God and his Messiah. (By that time, all Israel will have come to believe.)
The Tribulation will be horrible, but will be a cakewalk compared to the Wrath of God.
