The IDF Spokesman Twitter account for Arabic has published guidance for Gazans to evacuate along two main roads between 10am and 4pm today (October 14th).

#Urgent Important statement for residents of Gaza City In recent days, we have appealed to you to leave Gaza City to the south of Wadi Gaza in order to preserve your safety. I would like to inform you that the IDF will allow movement on the indicated streets without any harm between the hours of 10:00 - 16:00. For your safety, take advantage of the short time to move towards the south - from Beit Hanoun to Khan Yunis. If you care about yourself and your loved ones, go south as instructed. Rest assured that Hamas leaders have taken care of themselves and are taking cover from strikes in the region. Residents of Al-Shati, Al-Rimal and West Al-Zaytoun will also be allowed to move on Daldul and Al-Sanaa Streets towards my street By At Saladin and the sea
if they're posting it to twitter, hearing in mind power and internet are totally cut in Gaza, this is for YOU to read, not Palestinians.
when civilians are inevitably killed they'll tell the press that it was "clearly communicated through official channels" and everyone online will just take the IDF at its word.
Sure, but the act of telling the UN and social media was to make the case of the fabled civilian insurgent when these people are killed, including the ones killed by IDF when travelling along the very roads in the graphic.
