The National Hurricane Center is tracking two tropical threats within the Atlantic Hurricane Basin. One is about 800 miles east southeast of the southern Winward Islands and the other is near the east coast of the Yucatan Peninsula.
The National Hurricane Center began issuing advisories for Potential Tropical Cyclone #2 at 5pm on June 18; this is the first time that the National Hurricane Center issued advisories for a storm that has yet to officially form. Showers and thunderstorms associated with a tropical wave have become a little better organized since yesterday. Some additional development of this system is possible during the next couple of days before environmental conditions become less favorable for tropical cyclone formation. This system is forecast to move to the west-northwest at near 20 mph toward the Windward Islands and northeastern South America during the next two days, and interests in these areas should monitor its progress. Regardless of development, locally heavy rains and gusty winds are likely to spread over portions of the Windward Islands Monday night and Tuesday. An Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate this system on Monday, if necessary. There is a 60% chance that this system will develop over the next 48 hours.
