Members of a migrant caravan that formed in Honduras are charting their movement daily.
Organizers have told CNN they still don't know exactly which route they'll take. Much depends on the Mexican government and what routes the caravan is allowed to travel, whether its members are detained or held in certain areas and whether the group is provided with buses to speed their journey.
There's a possibility some members will split off and try to make their own way to the US-Mexico border. Others have decided to stay in Mexico -- or return to their home countries.
Here's what we know about their journey:
- The safest route would take them to Tijuana, across the US border from San Diego. A large caravan that crossed Mexico in the spring -- and also drew ire from President Trump -- took more than 30 days to reach Tijuana from Tapachula, Mexico -- a city this caravan departed on Monday.
- Right now the closest border crossing to this caravan would be between Matamoros, Mexico, and Brownsville, Texas, more than 1,000 miles away from the group's current location. But heading that way is considered a more dangerous route.
- To date, the caravan has traveled about 20 to 30 miles a day, trekking largely on foot and also hitching rides on passing vehicles when possible. If it continues at that rate, reaching Tijuana could take months, and reaching Matamoros could take weeks.
