The National Hurricane Center (NHC) is continuing to monitor the development of invests 93L and 94L in the Atlantic, and forecasters now say there’s a high chance they will become tropical depressions or tropical storms in the coming days.

The storm, the second Atlantic hurricane of the season, is approaching the Portuguese islands west of mainland Europe.

Hurricane Gabrielle will blast through the Azores before reaching Portugal as a non-tropical system, following its week-long journey. Gabrielle is moving rapidly toward the Azores — a group of nine volcanic islands about 740 miles west of Portugal — where hurricane warnings are in effect.

Hurricane Gabrielle passed Bermuda Monday night as a powerful Category 4 hurricane and is moving into the open Atlantic, the NHC said.

Hurricane Narda continued to churn in the waters of the Pacific Ocean on Wednesday, after the National Hurricane Center said on Tuesday that the system had reached Category 2 strength. Narda is the latest of several named systems to spawn in the Pacific so far this year,

Gabrielle strengthened into a major hurricane in the Atlantic Ocean on Monday but was forecast to remain away from land.
