Invest 93L which has a 20% chance of development according to the NHC is currently moving across the Eastern Caribbean and South of Puerto Rico. Although Puerto Rico avoided the brunt part of the system, moisture increase is still felt and some of the bands that the system can generate can move across Puerto Rico [...]

As we are under a drier air mass, today, friday, will be a sunny and nice day to go out. However, for the rest of the weekend, widespread rain across the island is expected associated to the passage of the tropical wave across the area. The effects of the tropical wave will start to be [...]
