.DISCUSSION...

Fresh to strong easterly winds will prevail today as Major
Hurricane Beryl passes south of the area today. Rainfall and
thunderstorms associated to Beryl will reach the region today.
Therefore, RH values will be high. In addition, KBDI values
continue below the critical threshold. A low fire weather risk
continues across the islands. However, we urge people to stay
inform with our latest updates.
