El Nifio may bring a wetter winter and spring to Florida

By: Clyde W. Fraisse
Climate Extension Specialist, Department of Agricultural and
Biological Engineering, Gainesville, Florida

Conditions across the equatorial Pacific Ocean started shifting from neutral to El Nifio last June
and now have warmed to weak El Nifio levels. During the Aug-Oct season, there is an
approximately 80% probability of maintaining at least weak El Nifio conditions, and a 19%
probability of returning to ENSO-neutral conditions.

El Nifio could have dramatic impacts on the climate of the Southeast for the remainder of 2009.
First, El Nifio hinders hurricane development in the Atlantic basin and leads to less active
seasons. The NOAA National Hurricane Center recently lowered the hurricane season outlook,
now predicting a near- to below-normal Atlantic hurricane season, as the calming effects of El
Nifio continue to develop. However, scientists cautioned that the season's quiet start does not
guarantee quiet times ahead. The season, which began June 1, is now entering its historical peak
period of August through October, when most storms form.

El Nifio events that develop early in the summer can also lead to drier than normal conditions
across Alabama and Georgia in the late summer and early fall. However, El Nifio's strongest
impacts on the Southeast occur in the colder months, bringing wet, stormy, and cool winter and
spring seasons to the Southeast with many implications to agriculture in Florida.

Winter vegetables such as tomato and green peppers generally yield less during El Nifio years
than during Neutral or La Nifia years. Most soil-borne pathogens and fruit quality problems
increase in El Nifio years. Fruit quality problems like gray wall and bacterial and fungal diseases
that are typically associated with wet climates can be more prevalent during El Nifio winters.
More information about potential impacts of El Nifio on winter vegetables can be found on the
following EDIS publication: Using Seasonal Climate Forecasts: Risk Management for Tomato
Production in South Florida.

Nutrient management can also be affected by a wetter winter and spring as the frequency of
leaching rainfall events increases, causing nutrients, mainly nitrogen to be washed out of the root
zone, especially in fields irrigated by seepage irrigation. Recent studies demonstrated that during
El Nifio years, at least one leaching rainfall event of 1.0 inch or more in 1 day occurred in most
locations where winter vegetables are grown in Florida and two of these events occurred in 9 out
of 10 years.

El Nifio may also impact other commodities; in general El Nifio years are good for winter pasture
due to wetter conditions. However, growth may be slower due to increased cloudiness and
consequent decrease in solar radiation. In the case of forestry, El Nifio plantings (wetter
conditions) are generally well established. However, under such conditions, plantings in very low
lands might be avoided to minimize losses as excessive rains might drown seedlings. Wetter
conditions may also have a negative impact on harvest operations.

In the case of temperate fruits (peach, nectarine, blueberry, strawberry) El Nifio conditions
generally result in increased chill accumulation in the early part of the winter (Nov.-Jan) and can
reduce the need for oil or other dormancy compensating sprays in peaches and blueberries. This
year growers can keep track of chill accumulation by checking the AgroClimate chill
accumulation tool that calculates the number of chill hours and chill units accumulated for all
Florida Automated Weather Network (FAWN) stations across the state
(http://www.agroclimate.org/tools/ChillAccum/). Cooler rainy conditions may slow development
rates in some perennial fruit crops such as strawberry. Lower levels of solar radiation resulting
from cloudy conditions may also affect growth in some cultivars. Additionally, conditions may
favor the development of fungal diseases such as Anthracnose and Botrytis fruit rots. Crown rots
caused by Colletotrichum and Phytophthora species and angular leaf spot (Xanthomonas
fragariae) are other diseases that are favored by cool wet winters. Thus, in contrast with the 2008-
09 winter season, when we had a La Nifia year that was typically drier than normal and
consequently had very little disease, growers should be alert and prepared for a coming season
with potentially higher disease pressure.
