I had no specific plan for the day except to begin it early.
I walked across the river and was surprised by the water level. The base of the island was submerged. The walkways on either side of the river were also many feet under water. (Note where the trees emerge from the water. That is where the shore was a week ago.)
Continued across the bridge and into Trastevere...through a farmers market.
This is one of my favorite things about produce here in Italy - the habit of offering up ad-hoc vegetable mixes for soup-making. From week to week the mixes change depending on the harvest. And when you've made your purchase, and the vendor is handing you your bag, they will often grab something - celery greens or parsley - and stuff them in your bag as a bonus.
Kept walking up and up and up through a series of lookout points...
And managed to reach the Janiculum a few minutes before noon. Looking north west, there was weather clearly heading towards the city.
The Janiculum is a hill where, each day, a cannon is fired precisely at noon. Noon arrived, the cannon went off - it was loud! And next the weather arrived. In the absence of an umbrella, I found shelter in an archway to wait it out and then walked back home.
