Weather
Departed having a destination and an alternate. Weather at all airports was IMC. As we prepared for the approach to destination we were faced with only one option due to winds and visibility conditions. We executed the RNAV approach and had to execute a missed approach. After evaluating the current fuel condition and weather we proceeded to our alternate. While on the ILS approach; the weather deteriorated rapidly dropping to 700RVR. We cancelled the approach and requested a delayed vector to gather information and come up with a plan of action. The weather over our alternate kept getting worst. After communicating with dispatch we decided to go to another alternate with a current visibility of 2 miles. We were almost about 15 miles away when we became aware that the current conditions were dropping rapidly. From my seat I could see that airports south of my position were under clear skies while to the north were completely IMC. With the little fuel onboard and the meteorological trend; I couldn't risk to execute an approach that could end with a missed approach. I just didn't think I was going to have enough fuel afterwards so we requested ATC to vector us to the most suitable airport south of our position with a long enough runway. We requested ATC to provide us with the necessary information about the airport (frequencies; etc). We didn't have charts for the airport since it is not an approved airport for our operations. Nevertheless it was an airport with a long enough runway; an air carrier service terminal; Security Identification Display Area (SIDA) ramp and most important; current weather conditions assure us with a safer approach to a landing environment within safe distance due to our current fuel onboard remaining conditions. At the end; my plane with all of my passengers and my crew were safe on the ground.
