Tropical Storm Andres is close to hurricane strength and will likely grow even stronger during the next 48 hours perhaps becoming a Category 2 hurricane by Sunday morning. Andres is located about 795 miles to the south-southwest of the southern tip of Baja California and will continue to track west-northwest at 9 mph today. Sustained winds are currently 70 mph and is not far from becoming the first hurricane of the 2015 Tropical Season in the East Pacific Basin.
Andres will continue to track over warm ocean water and through weak environmental vertical wind shear. The mid-level ridge that is steering this storm will weaken today and this should allow Andres to track more northerly later today. However that ridge will likely restrengthen and turn Andres back more to the west this weekend. By early next week the storm will have moved into an area of cooler water and higher shear, sending the storm into a weakening trend. Andres will stay over open waters and will not directly impact any landmasses. The only noticeable effect of the storm will be rough surf along the Mexican coast.
We are also watching an area of showers and thunderstorms several hundred miles south-southwest of the Gulf of Tehuantepec. This tropical wave will track west-northwest this weekend though an environment somewhat more favorable for development. This tropical wave may become more organized during the next 48-72 hours.
Elsewhere across the East Pacific, no development is likely for at least the next several days.
