There’s not much in the way of details so far. It apparently takes about 9 hours for drones to fly from Iran to Israel. Reports from Iraq say the drones have been heard flying overhead. The launch of missiles—faster cruise missiles and possibly even faster ballistic missiles will be timed so that the various aerial weapons will arrive in the area of Israel simultaneously. Jordan is said to have opened its air space to Israeli jets to attempt to shoot down the drones.

JUST IN: Iran will likely "synchronize" their drone attacks with "faster moving" missiles which could be launched closer to the time the drones arrive.
The Iranian launched drones are "suicide drones" which will take hours to reach Israel.
Israel is preparing for the attack by launching aircraft and evacuating military bases.
According to the New York Times, the slow moving suicide drones could be used a decoy to distract Israeli defenses to make way for the missiles.
"In order to intercept these launches, we have the circles of protection from both the Navy and the Air Force on several layers, and we have additional circles of protection from the US military," the IDF said.

Via Megatron:
It takes 9 hours for drones to reach Israel, 2 hours for cruise missiles, 12 minutes for ballistic missiles and only 400 seconds for hypersonic missiles.
BREAKING:  Yemen is also now attacking Israel with dozens of missiles.
There have also been claims of an Iranian cyber attack:
Israel shut down by Iranian cyber attack telling residents to prepare for war
A cyber attack has hit Israeli websites as Iran and its proxies prepare for a retaliatory attack.
No doubt more information will be coming in as events develop.
"The Lebanese newspaper Al-Akhbar, suggests there may be a diplomatic way out that avoids full Iranian military retaliation. Iran is "proposing the following: If a ceasefire is reached in Gaza and Israel does not attack the city of Rafah, it is ready, in order to reduce escalation and tension, not to take any action against Israel at the present time," the newspaper stated."
Oops... just a little too late, I guess. /sarc :(
And we're off.
