Puerto Rico, this week

Carraízo reservoir's water level fluctuated over the course of the week, according to the latest readings in the ajustes band. The week began with a 7-centimeter rise, bringing the level to 37.86 meters, or 0.86 meters above the control line. That gain was short-lived: the following day the level dipped slightly by 1 centimeter to 37.85 meters, still 0.85 meters above the control line.

The decline continued and accelerated in the days that followed. On the ninth day tracked, Carraízo dropped another 3 centimeters, settling at 37.82 meters, or 0.82 meters above the control line, with officials estimating the reservoir was on pace to reach the control line in roughly 27.3 days at that rate. Overnight, the drop steepened further, with the level falling 6 centimeters to 37.76 meters — 0.76 meters above the control line. That faster pace of decline shortened the projected timeline to reach the control line to roughly 12.7 days.

Taken together, the week's readings show Carraízo moving from a modest rise early on to a sustained and quickening decline by its end, with the projected number of days until the reservoir reaches its control line cut by more than half over the course of just a few days.
