This Sahel rainfall forecast is based on many of the same factors as the current seasonal hurricane forecast and indicates that Western Sahel rainfall conditions will be distinctly above the rainfall conditions of the 1990-1993 period. We thus judge Western Sahel rainfall not to be an inhibiting influence on Atlantic intense hurricane activity during 1995 in comparison to what it has been for most of the last 25 years. Rainfall has started slowly this year but has shown significant increases in the last ten days of July. We expect Western Sahel rainfall conditions to pick up in the months of August and September and for slightly above average amounts to have occurred by the end of the rainy season. These two June-July measurements indicate an enhancing influence on this year's hurricane activity.
