Thousands of migrants who arrived in October's caravan are camped out in Mexico, waiting to make asylum claims in America. Yet another, bigger caravan is still preparing to make a similar trek, The San Diego Union-Tribune reports.

An estimated 15,000 Hondurans have organized to leave their violent, poverty-stricken country, per Spanish-language media and migrant rights activists. "They say they are even bigger and stronger than the last caravan," migrant activist Irma Garrido tells the Union-Tribune. And that's not counting Guatemalan and Salvadoran migrants who are expected to join along the way.

After traveling a few thousand miles north, most migrants from the last caravan still haven't been allowed to claim asylum in the U.S. They're waiting in makeshift tents in Tijuana as human rights groups' and government resources run dry, creating what The Washington Post calls Mexico's own "border crisis."

That's seemingly why this new caravan won't rush to the U.S.-Mexico border right away, Garrido tells the Union-Tribune. Previous arrivals don't have visas to work as they wait to cross the U.S.-Mexico border, so these newcomers will stay in southern Mexico and look for work there. Newly inaugurated Mexican President Andrés Manuel López Obrador has promised to expand work permits for Central American migrants. The U.S. and Mexico have also agreed to devote billions of dollars in aid to slow Central American migration.
