Use local resources if you can
we were in Costa Rica a couple years ago and for two years I was a US Peace Corps Volunteer assigned to Puerto Limon. I know Sixola, Changuinola and Puerto Limon and have political contacts that represent Puerto Limon and surrounding areas. Private message me if your situation becomes critical (you be the judge). I am in Buenos Aires, but can call a diplutado / congressman, who has his PHd and is a best selling author. He grew up in Limon. He is a very capable and resourceful man with contacts at the Presidential level.
His name is Dr. Quince Duncan and if you deem your situation an emergency, for whatever reason, I am sure he can and will coordinate your evacuation from danger.
Meanwhile, I would contact the Red Cross, Cruz Roja,(sometimes it is better to call the America Red Cross and have them Contact Cruz Roja in your area via high level channels)... if the phones or internet are still up, report in to your countries embassies in Costa Rica and Panama and ask for suggestions.
Here is a time to get to know the people, the culture and locate other valuable resources on your own. You will be OK I believe, just delayed and that might not be a bad thing.
Keep us posted, by your post I see that at least you have communication out...use it... xfiltrate
