Puerto Rico is in the middle of its second major blackout in less than a week, and Puerto Ricans are getting fed up.

The power outage was caused by heavy machinery that was being used to remove a collapsed transmission tower. Power is expected to be restored over the next day and a half.

A single tree plunged more than half of the island's population into darkness. It was a humbling reminder for some that power restoration is not yet complete in more remote parts of the island.

Puerto Rico's governor had been locked in tense negotiations with the U.S. Treasury over terms governing $4.7 billion in loans that Congress approved to help the island recover from Hurricane Maria.

As of this week, many Puerto Ricans have been without power for six months. They've been waiting not since Hurricane Maria, but since Hurricane Irma, which struck two weeks earlier.

The island's government wants overhaul education, including by introducing charter schools and closing some public schools But critics say they're using Hurricane Maria damage as an excuse.

Many Mexicans deal with heartbreak by listening to rancheras, traditional songs from Mexico's countryside. One young woman found a connection to her ancestors through the sounds of guitars and tears.

In Puerto Rico, an explosion at a major power substation plunged San Juan and the surrounding areas back into darkness on Sunday. The blackout was a further setback in the ongoing efforts to restore power to the island.

The agency says it has been working on transitioning distribution to the Puerto Rican government but has not finalized it. Wednesday's date "was mistakenly provided," a spokesman said.

The Federal Emergency Management Agency has delivered millions of meals and gallons of water since Hurricane Maria devastated the island. Four months later, it says that help is no longer needed.
