000 ABPZ20 KNHC 182333 TWOEP TROPICAL WEATHER OUTLOOK NWS NATIONAL HURRICANE CENTER MIAMI FL 500 PM PDT SUN OCT 18 2015 For the eastern North Pacific...east of 140 degrees west longitude: The National Hurricane Center is issuing advisories on Hurricane Olaf, located about 1500 miles east-southeast of the Big Island of Hawaii. Showers and thunderstorms extending several hundred miles off the coasts of southern Mexico and Guatemala are associated with a broad area of low pressure, which is interacting with strong northerly winds blowing over the Gulf of Tehuantepec. Although some development is possible during the next couple of days, a tropical depression is more likely to form later this week once the low begins to move west-northwestward and then northwestward away from the Gulf of Tehuantepec. Interests along the southern and southwestern coasts of Mexico should monitor the progress of this system during the next few days. Regardless of development, heavy rains are possible over portions of southern Mexico, Guatemala, and El Salvador during the next couple of days. * Formation chance through 48 hours...medium...40 percent * Formation chance through 5 days...high...80 percent $$ Forecaster Berg
