The National Hurricane Center indicated Wednesday that the tropical wave has a 60% probability of becoming a tropical depression in the next 48 hours and an 80% of doing so in the next five days.
The IMN’s Juan Diego Naranjo, affirmed that the latest analysis on tropical wave no. 30 is foreseen to arrive in Costa Rica this Thursday afternoon, expected to interact with the intertropical convergence zone favoring a rainy scenario.
“If this tropical wave becomes a tropical depression, it would happen in northern Central America by the weekend. Due to its possible position and strengthening, there is a high probability of indirect influence towards Costa Rica,” says the meteorological warning issued Wednesday afternoon.
According to Naranjo, the projected direction indicates that it would be off the coast of Honduras where it develops as a tropical depression, that is, with associated winds between 50 and 69 kilometers per hour. From 70 to 119 it is considered a tropical storm and 120 onwards a hurricane.

Landslides are common during this time of year, as heavy water-laden slope soil, rock, etc. will succumb to the forces of gravity. Slides can cause disastrous flooding, particularly when landslide dams across streams are breached, and flooding may trigger slides.
