Rain Returns To Southern Brazil, Flowering Still Not Likely

By Andy Karst

           Kansas City, August 13 (World Weather, Inc.) – Dry weather occurred in Brazil Tuesday before rain increased in northern Parana Tuesday night.  The rain was not likely great enough to stimulate flowering and with most of the rain during the next couple days becoming less intense and shifting to the northeast new flowering does not appear likely.  . Some cooling is expected in the south today and Thursday, but there is no risk of crop threatening cold for the next two weeks.  The Central Highlands of Vietnam is still expected to see an increase in rain Thursday into next week.  Most of the rain should be light, but enough rain should fall to prevent excessive dryness form evolving.   

BRAZIL

            Rain increased in far southern coffee areas Tuesday night and by dawn this morning Londrina, Parana received 19 millimeters of rain.  The rain was not likely great enough to stimulate flowering.  High temperatures were in the upper 20s and lower 30s Celsius.  Lows this morning were in the teens most often with readings of 9 to 11 from portions of northern Sul de Minas to central Minas Gerais and northern Zona de Mata. 

 

       A weak cool front will drift northward from Parana through Sao Paulo to Sul de Minas and Rio de Janeiro today and Thursday. The frontal system will not induce much temperature change, but a few showers may pop up briefly. The precipitation will be insignificant relative to previously flowered coffee. No change in crop or soil moisture will result and flowers will continue to be aborted after prematurely opening as a result of significant rain a couple of weeks ago. The few showers that evolve will produce 1 to 8 millimeters of rain and will favor areas from northern Parana to coastal Sao Paulo and Rio de Janeiro. Other coastal showers will be possible on a near-daily basis in eastern Bahia and Espirito Santo Thursday of this week through the weekend and into the majority of next week. Rainfall along the coast could reach 5 to 15 millimeters on any given day, but nearly all of the precipitation will stay east of coffee and cocoa production areas.

            Temperatures will trend slightly cooler today into Thursday with highs in the lower to middle 20s. A couple of extreme highs in the upper teens are possible due to dense cloudiness today in the far south. Otherwise, daily highs through the next week to ten days will be in the 20s south and in the middle 20s to lower 30s north. Lowest temperatures at night will slip into the range of 6 to 9 degrees periodically from Parana to Sul de Minas while varying 10 to 19 in most other areas with Bahia and northern Espirito Santo warmest. A couple of low temperatures near the Atlantic coast may fail to cool below 20.
